iPhone firmware 2.2.1 – Jailbreak & Unlock now!

iPhone 2.2.1 update firmware is a small bug fix release, it does not bring anything new to the table. We are still waiting for the real deal, the 2.3 update!

Anyway, for those who would like to update anyway to 2.2.1 and still be able to jailbreak and/or unlock, it is now possible!

Before you proceed, remember :

1. GOLDEN RULE: If you have a 3G iPhone running 2.2 firmware and you want to keep your ability to use yellowns0w (or the option to use it in the future) do NOT use QuickPwn, and do not use the official ipsw or the iTunes update process without using PwnageTool.
2. Yellowsn0w will NOT work with the baseband version (02.30.03) that is present in the recent 2.2.1 update – you will need to create a custom ipsw that will allow you to update safely without affecting the baseband.
