Yesterday Apple has released Firmware 2.2.1 update for iPhone and iPod Touch and tons of question started spawning into the minds of jailbreaked iPhone and iPod touch owner. First foremost question is, should we upgrade iPhone and iPod touch to firmware 2.2.1?
Here is reply from MuscleNerd of iPhone dev team, Answer is “No”. iPhone dev team is still investigating firmware 2.2.1 to find will it be possible to Jailbreak and Unlock iPhone and iPod touch after upgrading to firmware 2.2.1. MuscleNerd has released video on Qik which gives information on current situation.
Update: iPhone Dev Team has released QuickPwn 2.2.5 and PwnageTool 2.2.5.
Here are Notes from that Video.
iPhone 3G with Firmware 2.2.1
Upgrading your iPhone to firmware 2.2.1 will affect your ability to Unlock your iPhone 3G with yellowsn0w. Reason is Firmware 2.2.1 will upgrade your iPhone baseband to 2.30.03 where as yellosn0w is designed to work with baseband 02.28.00. One way you can upgrade your iPhone firmware to 2.2.1 is by custom firmware which will not update your baseband but that’s not possible as pwnagetool and quickpwn are still not updated for firmware 2.2.1.
iPod Touch 2G with Firmware 2.2.1
Musclenerd mentioned that even after upgrading iPod Touch 2G to firmware 2.2.1 doesn’t affect the ability to jailbreak and they can still tethered jailbreak iPod Touch 2G 2.2.1. The Dev Team working on exploit to allow an untethered jailbreak.
