2.2 working with non iphone at&t sim.
i bought an iphone 3g for 300 locally. i originally had an iphone 2g with 2.2 quickpwned. the 3 g was already updated to 2.2 but i could not get a signal... so. i jailbroke it and read all the sites. i thought i was just going to have to sell it but i tried one more time. reinstalled itunes/ restored from itunes/let it download the software/ set up as a new phone. and low and behold it activated me..... so now i have a 3g iphone activated but not jailbroken. can i still jailbreak it and not lose my activation. btw the sim is a 3g originally from a slvr.
