hi.....i accidentally downloaded the new iphone 2.2 software(from apple) to my jailbroken and unlocked(via sim adapter) iphone 3G(u.s. version),(was working properley), the phone has the message no service in the top left hand corner, i have since managed to re-install the 2.1 software back onto it, using quickpwn 2.1, but after many resets and trys, i can still get no signal, even with the old software back on!!, briefly after a reset i see the o2 signal appear for a couple of seconds and then deminish, does anybody have a fix for this or any help appreciated! i am on o2 network pay-as-u-go in the uk...just checked out the dev team web page, where it states iphone 3G customers should not download, until a another version of this unlock is available!!! doh....thanks 4 any replies,
