We told you before that i0n1c is working on the Untethered Jailbreak for iOS4.3 on iPod/iPad1/iPhone all previous iDevices. And he demonstrated a video of iPad showing Untethered Jailbreak. If you have missed it so you can see here.
Because so many people are asking for an ETA:
I am pretty sure that the untether will be released before the next weekend. I was using older kernel patches that caused lagging on the jailbroken device. I will change that and then port it to the other devices and release.
The ETA told by him is this Week. It is also expected that iOS4.3.1 will also be pushed by Apple some time soon because the iPhone4 was jailbreaked in Pwn20wn Contest and Safari browser have still got some bugs which can let the jailbreaker easily break into you iDevice and steal things from you like your Contacts and etc.
Till now no Particular date is given for the release but it will be out some time soon. Meanwhile save your SHSH Blobs to stay safe in Future. There wont be any new tool for this Jailbreak, it is said to be ported to Redsn0w.
And obviously you don’t need to Update to iOS4.3 whether the Jailbreak is out because many of the Cydia Tweaks won’t work like Winterboard and so on. The Tweaks which require Mobile Substrate won’t work. So stay from the Update. Specially people who rely on an Unlock.
