在Dev-Team Blog上看到說……
Yellowsn0w will NOT work with the baseband version (02.30.03) that is present in the recent 2.2.1 update. If you want to use Yellownsn0w you will need to create and restore using a custom .ipsw that will allow you to update safely to 2.2.1 without applying the 02.30.03 baseband update. You’ll then have a 3G iPhone running 2.2.1 with an older baseband version that is still vulnerable to yellowsn0w,
貌似不支持2.2.1的官方固件生以後的iphone(因爲baseband升級了……)但是可以用自己修改過不升級baseband的升級包升級來達成yellowsn0w解鎖~
