Undoubtedly, the iPhone baseband unlocking is not frustration less, and it is one of the most demanded services across the iPhone users, especially the AT&T users are tightly bound in their contract with the carrier who doesn’t even allow them to use their iPhone unlock-ly after the expiration of the contract with the carrier. However, the iPhone Baseband Unlock comes possible through the jailbreak tweaks and hardware exploits generated by most skilled developers around the world. We already have coupled of iPhone baseband unlocks present in the market by these individual hackers but still the whole unlocking process is not frustration less, as Apple is actively protecting its hardware with new software updates.

“We’ve just received word of a spicy strategy change, to be enacted this Sunday, that’s sure to please the AT&T iPhone-loving masses. On Easter, select Ma’ Bell customers with iPhones–those off-contract with accounts in good standing–will be able to request a carrier unlock for their device.”

But now according to a new inside report from AT&T suggests that carrier is finally considering to unlock the off-contract iPhone users from this Sunday. The report comes from the Engagdet, who reports that they have received a tip from their sources that AT&T is going to unlock off-contract iPhone basebands for the loyal users, means now you would be finally able to use your iPhone with other carrier SIM’s, and also be able to use your AT&T powered iPhone worldwide with other carriers.

Some users have recently reported that they are able to get their iPhone unlock from the AT&T on contacting the Tim Cook office. However, now from Sunday, you guys will be able to unlock your iPhone  from AT&T officially be calling the AT&T customers helpline. The unlocked iPhone would be a great option for the users, as it allows users to put any carrier SIM on the iPhone and allow them to use internationally.

Almost two – three weeks ago, Apple released the new major iOS 5.1 update in the public during the announcement event of new iPad 3 in San Francisco. The new iOS 5.1 comes in a really surprising way, as Apple completely skipped the release of iOS 5.1 GM version to the developers and directly opted to launch the iOS 5.1 at the media event. Just like always, the iOS hackers quickly released public statements not to update the iPhone 4/ 4S & iPad 2 devices to the latest iOS 5.1 firmware version, as it expected to come up with a brand-new baseband update that for surely lock the million of iPhone 4S and iPhone 4 back on the carrier cellular and users again have to use their original service provider. Despite pre-announcements from hackers, still thousands of users have updated their devices to the latest firmware version.

The users quickly jumped to the iOS 5.1 without even reading the complete informative notes from the iPhone DevTeam on which they have stated clearly that updating your device to the latest iOS 5.1 will cause you to lose your unlock status, and as well as the untethered jailbreak status on your devices. Hackers very deeply warned the users not to update their devices to iOS 5.1, as with the iOS 5, Apple blocked the Blobmonster feature, and there is no way to downgrade the newer generation devices to the older iOS versions, even with the saved SHSH blobs, and therefore, many users now stuck on the iOS 5.1 without even a jailbreak access to their devices.

It is reported by the developers in the community that the users around the world quickly adopt the iOS 5.1 update, and forget about all the other things. The hackers and developer’s highlights the Over-The-Air updates feature behind this update rate, as many of the users do not familiar with the OTA updates, and to clear out the banners from the iPhone / iPad screen quickly pushes the update button to sort out the issue.  So for those who are seeking to downgrade iPhone 4S / iPad 2 from iOS 5.1 to iOS 5.0.1 or iOS 5.0, there is currently no method publicly available to downgrade the later generation devices, so don’t ever waste your time in trying anything on your device.

The new iOS 5.1 firmware update brings a lot of new challenges for the iOS hackers, and as well as for the baseband hackers and the developers over the Gevey SIM & TP-SIM labs. iOS 5.1 brings a new update to both iPhone 4 & iPhone 4S baseband’s, while the first baseband of iOS 5.0 on iPhone 4 is not yet completely unlocked, and most of the users are crying due to this, but on the same side, the iPhone 4S users are enjoying the latest iOS 5.x.x updates, as the iPhone 4S all baseband’s are completely unlocked with the Gevey SIM interposer. With the iOS 5.1 update, the iPhone 4’s baseband has been updated to 04.12.01 and the iPhone 4S’ baseband updated to 2.0.10.

How To Unlock iPhone 4 Baseband 4.12.01 And iPhone 4S Baseband 2.0.10?

However, many of you have been the same question running in your minds right now, just like you, we also have the same question in our mind, but along with this question we have some points to clear out some facts regarding the iPhone 4 and iPhone 4S baseband unlock on iOS 5.1.  First of all, if you have ever upgraded your device to latest iOS 5.x.x firmware version, then you will be never able to downgrade your device. In addition to this restriction, let us remind you that from the very first day, there was not the solution to downgrade the baseband of your device, and especially the iPhone baseband so if you have upgraded your device to the latest iOS 5.1 without preserving the baseband, then it means you are running out of luck at the moment. To those who are looking for 04.12.01 iPhone 4 baseband unlock, the first iOS 5.0 baseband update is not yet completely unlocked, so definitely the newest baseband updates comes up with some more security over the chip, and no-doubt it would require a lot of time to unlock the baseband on the latest iOS 5.1 firmware version.

On the other side, if you are locked on 04.11.08 iPhone 4 baseband with iOS 5.0.1, we will suggest you to stay there, as we have heard the couple of reports from the developers in the community that 04.11.08 baseband unlock is possible, and under the general testing. So it means that we can see unlock for 04.11.08 baseband unlock.

To Stay Safe With iPhone 4 Unlock:

There is a simple task to stay safe, just keep your phone away from the iTunes sync, and as well as ignore the iOS 5.1 update, because if you upgrade your device to the latest iOS 5.1, you’ll surely lose your unlock status.

Update: R-SIM announced that they are launching their fourth-gen “R-SIM” to finally unlock iPhone 4 “04.11.08″ baseband on iOS 5.0 / 5.0.1 / 5.1 

Still facing iPhone 4 “04.11.08” Baseband Unlock Problem? – It’s been five months that Apple released the first public build of iOS 5 for the general public on the iPhone 4S announcement, and iOS 5 is appeared to be the major iOS release, as the new-generation iOS 5 comes with the number of new features, services, and of course new hurdles for the iOS Hackers and users who have been jailbreaking and unlocking their devices with the free and paid alternative methods. The new iOS 5 brings the “04.11.08” baseband for the iPhone 4 users, and as we have stated before in the couple of unlock regarding updates, the new baseband comes with extra security from Apple that prevents users and hackers from breaking the restriction and turns their devices into a simple iPod Touch.

However, before any iOS public launch, the hackers warn users not to update their devices too quickly on the latest iOS 5 firmware version, but still million of users quickly updated their devices to the latest iOS 5.0 build without even knowing the facts, and no-doubt loses their unlock and jailbreak status. However, the iOS 5 jailbreak is possible, but it appears that hackers and developers around the world are still not able to unlock the iPhone 4 “04.11.08” baseband, despite claiming hands-on the couple of working exploits that allow you to unlock iPhone 4 “04.11.08” baseband. Recently, we have reported you about the confirmation from Gevey Team that they are testing the “04.11.08” baseband unlock on their labs, and working on the build to make it more stable before the public launch.

On the other side, Apple had already launched the iPhone 4S with pre-installed iOS 5, and millions of users purchased the device from different carriers on packages, but still users around there looking for unlock solutions for the iPhone 4S that allows them to put other carrier SIM cards into their devices and let them access the network. Just right after the iPhone 4S launch, we had reported you that iPhone-Dev team reports that they have an exploit to unlock the iPhone 4S on several baseband’s, but they had not announced any launch date. While on the same month, Gevey again comes to the media and announced the first ever iPhone 4S baseband unlock for these baseband’s:

Standing on the same edge, Gevey again claimed that they not forgot the iPhone 4 baseband unlock users, and their team is still working on the exploit to make it more successful, but they decided to launch the iPhone 4S unlock first, as many users moved themselves to the newer iPhone 4S devices, and therefore, they believe iPhone 4 is pretty older now for the users, but still they have been working on the iPhone 4 “04.11.08” baseband solution.

While there were only two solutions to unlock iPhone 4 baseband on the iOS, the software based and the hardware one. Discussing the software based unlock solution for an iPhone 4 baseband, we have reports that iPhone-DevTeam in collaboration with other prominent baseband hackers are working on the baseband cracks, but still they have lot of things more important the iPhone 4 “04.11.08” baseband unlock with UltraSn0w. As with the iOS 5, Apple blocked the major feature of the iOS jailbreaking the SHSH Blobmonster that allows hackers and users to save the SHSH blobs of the different devices, and then give access to downgrade their devices to the specific iOS version without any kind of hurdle.  However, reportedly, the whole iPhone DevTeam is currently working on the Blobmonster, and the iOS 5.x.x untethered exploits for the A5 and A5X devices, and therefore, we are not going to see any Ultrasn0w update from them targeting the new iPhone 4S and iPhone 4 baseband unlock.

The Gevey SIM interposer unlock is referred to as a hardware based iPhone 4 baseband unlock, as in this unlock solution users have to trick the iPhone baseband with a hardware SIM cloning that allow users to easily fake the carrier restrictions on their devices.

Few days ago, we have reported you that iPhone Dev-Team has just released the tethered iOS 5.1 Jailbreak with Redsn0w 0.9.10b6 for the older generation device, and the users with iPhone 4 / 3GS, iPad and iPod Touch can upgrade their devices to the latest iOS 5.1 with the tethered jailbreak option, and can preserve their iPhone basebands for the Ultrasn0w unlock on iOS 5.1. However, in the quick update to the Redsn0w, iPhone Dev-Team mentions that they will soon release the new Ultrasn0w to unlock iPhone 4 and iPhone 3GS on iOS 5.1, but until now, they have not yet released any update to their Ultrasn0w tweak with the compatibility for iOS 5.1.

Many users have upgraded their devices to the tethered iOS 5.1 jailbreak to test the newer tweaks, and applications on their devices while preserving their basebands to unlock their device later with Ultrasn0w, but now it appears that developers over there just forget to push a new update to their unlocking tool, and therefore, the other developers out there got chance to introduce something new in the market to bring the Ultrasn0w unlock on iOS 5.1 with their little reverse engineered tweak. “Ultrasn0w Fixer,” the older tweak is just released back in the Cydia with the ability to fix the Ultrasn0w on iOS 5.1 to unlock the supported iPhone 4 and iPhone 3GS basebands on the iOS 5.1.

So now we recommend the installation of this “Ultrasn0w Fixer” to the users, who have been waiting for the official Ultrasn0w update from the iPhone Dev Team to unlock their device on iOS 5.1 with Ultrasn0w. The users with locked iPhone 4 baseband can unlock their device with the new Ultrasn0w Fixer installation on their device. The new tweak is not available on the public Cydia’s repository like the previous release of the update, instead this time you have to install the tweak directly from the developers’ private repository.

To install the Ultrasn0w Fixer to unlock iOS 5.1 you have add this repository in your Cydia, and then do a quick search for the “UltraSn0w Fixer”. Add this repository in your Cydia to get the tweak on your device: “http://repo.iparelhos.com”

Let, me clear you! The tweak doesn’t support any new baseband update unlock, and can unlock only those baseband that was already supported by the official ultrasn0w. The tweak simply fixes the Ultrasn0w to make it work on the iOS 5.1.

The day before we reported that Ultrasn0w will be updated on next Monday with the support of iOS 5.0.1. But it seems that there was some sort of miscommunication or misinterpretation of the update of Monday. The update of Ultrasn0w is now live in Cydia.

Today’s update of Ultrasn0w is not for any new baseband. This update is made to fix the status of Ultrasn0w on iOS 5.0.1 which was broken on this firmware. The current version of Ultrasn0w supports the following basbebands.

• 1.59.00
• 5.13.01
• 5.12.01
• 6.15.00

Those of who you are on old basebands can update ULtrasn0w to make it work on your iPhone running iOS 5.0.1.It has been more than a year since we last saw the Unlock. Till now no new baseband Unlocks have been seen so far. The only Unlock working for the new baseband is Gevey SIM. Many people owning an iPhone 4 are desperately waiting for an Unlock for 2.10 and above basebands.

The Dev-Team has successfuly Unlocked the iPhone 4S, where as the user of iPhone 4 are left in dark. Now we have to see if the Dev-Team can do anything with the new baseband on iOS 5 or not.

Thanks Brian Dardha for the tip.

Let me share a quick news regarding the iPhone 4S baseband unlock with ultrasn0w, last week we got news from the iPhone DevTeam key member, Musclenerd that they are working actively on the iPhone 4S unlock with ultrasn0w. This week, MuscleNerd using his official twitter account announces that they were just able to dump the iPhone 4S baseband rom, which in directly means they have been just able to unlock their iPhone 4S baseband, and now just testing within few other developers before launching it in public.

MuscleNerd has not shared any time period on which they release this unlock in the public, he just announces their little progress about the iPhone 4S unlock that they have been successfully able to dump the baseband bootrom of the iPhone 4S. Dumping baseband bootrom means its quite easy to generate unlock for the iPhone 4S with software tricks.

According to him, the software code which connects the iPhone 4S with carrier network is presents in the internal rom of the device, and can easily modify with software tricks. However, they have not announced any date to launch this exploit in the public which allows users to unlock their devices.
