A good guide: http://www.breakitdownblog.com/how-to-install-iphone-221-firmware-on-jailbroken-and-unlocked-t-mobile-iphone/


Summary


A Summary of the information above is as follows:



  • If you have a 3G iPhone (2nd Generation), installing the 2.2.1 Firmware updates your baseband to 02.30.03, and blocks your ability to unlock the phone — allowing it to work on unsupported networks (like T-Mobile). You can still Jailbreak the phone however. So until unlocking this phone is supported, hold off on updating it using the normal Apple firmware — if you must update it, you can build your own custom firmware by using PwnageTool (Mac Only).

  • If you have a 2G iPhone (1st Generation) or a iPod Touch (1st Generation), installing 2.2.1 Firmware is fine — even though it updates your baseband, the way QuickPwn unlocks the phone still continues to work fine. So you are OK here in all cases.

  • If you have a iPod Touch (1st Generation), you can still apply this upgrade but you can only Jailbreak it while teathered to your computer. So you are still OK here.

I used the same instructions recently-worked like a charm.

One thing i would recommend is to make sure you are running THE MOST RECENT iTUNES, as when i went to update mine it was temporarily bricked.

Ended up having to put it manually into DFU mode, update iTunes and then "shift-click restore" it using the .ipsw given.

One thing I haven't done is apply 2.2.1, can we just apply that? Like the last short patch?

Yeah, i just "shift-click" restored it and then used Pwnage tool.

No dramas apart from reinstalling all my old apps lol
