I have a 2G 2.2.1 unlocked (Cydia/Quickpwn) iPhone that I attempted to upgrade to 3.0. I had purchased unlock software from autoiphoneunlocker.com and followed their instructions exactly. Shortly after I did, the phone was no longer recognized by iTunes and would not accept a charge with either the USB from MacBook or wall charger. Phone is now dead except it will still connect to internet and download emails using wireless network. I have tried a variety of suggested hard restore options and none have worked. Any suggestions? BTW, Auto Phone Unlocker has totally failed to support me in this problem and now will not reply to my emails. I would consider them an unreliable resource.
