Yea, i was so tempted on updated to 2.2. But i knew i should wait until the jailbreak 2.2 is released instead. Luckily :D. I love my jailbreak 2.1 just fine :P

word on the street is 2.2 is downgrade friendly so give that a shot. when you downgrade you will definately loose your data. sync your important info first. DFU and run with it. Get more info first because I know the 2g can be, but the 3g might as well get more info because 2.2 changes the 3g's baseband so wait a couple hrs if u can afford to. if not drop to 2.1, if its a no go just come back up.

I made the mistake of updating to 2.2 immediately, and it now cannot connect to the mobile network (using a simunlock chip). Is it possible to reverse the update, for example by restoring the iphone to the 2.1 firmware version that you have available on this site? I cannot find a clear guideline on what will be restored, kept, changed, or lost lost if I try to do this. i would appreciate any advice, or a quick explanation of why this would/wouldn't work. Thanks!
