iphone 3G 2.2 question

[mrguyname]

Hey guys my iphone 3g is currently on 2.1 firmware with 02.11.07 baseband version. I'm running tmobile with gevey3g sim adapter. If I want to update to 2.2 FW, should I just update to 2.2 firmware via iTunes and then jailbreak on quickpwn and forget about yellowsn0w since I'm using a simadapter? Or should I be using yellowsn0w to unlock anyway? Help me out, thanks.

There are currently 35 pages of people that can't get yellowsn0w to work. Stick with what you have until a final release is available.
