It has been revealed that iPhone software update version 2.2.1 does not break the iPhone Dev Team's methods of jailbreak. However, 2.2.1 does break the 3G software unlock, users have reported.

As every iPhone user should know, Apple released iPhone 2.2.1 firmware two days ago, addressing issues with photos saved from the iPhone Mail application and improving performance with the iPhone's web browser, Safari. Over at modmyi forums, user cash7c3 points out to MuscleNerd of the iPhone Dev Team who has been providing some updates on the iPhone 2.2.1 firmware. The user posts three points of interest for users of an Apple handset:

- 2.2.1 does not break the dev team's methods of jailbreak;
- 2.2.1 breaks the 3g software unlock;
- 2.2.1 does not break iPhone 2G unlock since the 2G baseband is not updated.

Those who benefit from using a jailbroken device are advised to wait until the dev team comes up with a solution to upgrade to 2.2.1 without losing the unlock.

“There is an iPhone and iPod update available in iTunes - it is numbered 2.2.1 (5H11a). Please DO NOT update. We will investigate and report back to you ASAP,” says the team on its blog. A video explaining what the update means is also available on behalf of the dev team.

The hackers will try and create a custom firmware update that delivers the benefits of the software update from Apple, but doesn't update the baseband of the first gen iPhone. With the new version of a tool like QuickPwn in their hands, users will be able to continue using their unlocked devices with carriers not yet supported by Apple, or download free applications from various repositories.

Softpedia doesn't condone jailbreaking / unlocking the iPhone / iPod touch or any other device. Using hacks may render your device unusable, or may considerably reduce the quality of your experience using the respective device. If you choose to download and install the jailbreak tools, you will do so at your own risk.
Unlocking / Jailbreaking your iPhone may violate your warranty or the EULA with Apple and/or your cellular service provider.
