iPhone Dev Team delivers 2.2 jailbreak with a warning

As promised the iPhone Dev team has delivered the 2.2 firmware jailbreak in the design of the Pwnage tool and Quickpwn for both Mac and Windows machines. that update seems to be the real deal breaker in regards to future unlocks.

Upgrading using iTunes can forever eliminate your chances of ever unlocking you iPhone 3G. The baseband has apparently been changed now so that it will be near impossible to unlock in the future. For those who still don’t quite understand the meaning of the baseband:

Baseband 101

The ‘baseband’ is the generic name given to the internal components of the iPhone that handle the phone calls and World Wide Web access. that ‘baseband’ is a tiny and different independent computer system that runs inside your iPhone, it is separate to the main system that handles the applications (such as newsletter and google maps) and it talks to the main part of the phone by an internal communications network. Think of it like a cable modem or other peripheral that is attached to your home PC that needs occasional updates. When a software update is released and presented to you within iTunes the

baseband is sometimes updated (to fix bugs or add new features). The 2.2 update for the iPhone 3G contains such an update, so running the vanilla updater straight away with iTunes will reprogram and update the baseband. that could be poor for undoubtful society, depending on your ultimate aim.

The iPhone Dev Team have included a few rules when upgrading to the iPhone firmware 2.2:

• GOLDEN RULE: whether you have a 3G iPhone and want potential soft unlock in the near future do NOT use QuickPwn, and do not use the official ipsw or the iTunes update process without using PwnageTool.

• Read item 1 again and again.

• Please read all parts of that post before downloading and using these tools.

• The ‘late 2008’ MacBook/air/pro line of computers have an issue with DFU mode. While it’s possible to go from Pwned 2.1 -> Pwned 2.2 (using PwnageTool), you can’t yet go from stock to pwned. whether in any doubt use a different machine.

• Choosing the exact tool is crucial. Be warned!
