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.
