Hey folks the last year we told you about that we will be having an untethered jailbreak by @comex on Christmas. But due to some issues he was unable to make it till the dead line and the Dev Team Said that they will come up with the backup plan. And they have released the backup plan for testers only.
A follow on Twitter asked @Musclenerd about the Jailbreak of the IOS4.2.1 which is only for testers.
L0ung3f1Y Asked: @comex or freakin release a jailbreak that does not require 4.2b3
MuscleNerd Said: So if @comex were to develop 4.2.1 untether, we warn all to save their 4.2.1 IPSWs for 4.3 untether via Monte
So, if @Comex releases the untethered jailbreak for iOS 4.2.1 then you will need to preserve your iOS 4.2.1 IPSW and SHSH to be able to get untethered jailbreak for the upcoming iOS 4.3. The Dev-Team can preserve the @comex Jailbreak codes to stay on the safe side. Till now the Redsn0w0.9.7b5 will be released soon for windows users to do an Untethered jailbreak for their iDevices.
And people who have recently bought iDevices and are on ios4.2.1 can perform a Tethered Jailbreak here.
