iTunes sync issue

[quicknight]

I apologize in advance if this is a repost, but I have not been able to find a solution to my "unique" problem. I purchased a USED iPhone 2G from a coworker and I was successfully able to jailbreak (blackrain) and unlock (bootneuter) the phone to use an AT&T gophone SIM card. The OS seems way slower (to be expected, I guess) than my 2nd Gen 32GB iPod Touch. I should say that I am a Sprint customer, using a Treo Pro and I only wanted to get the iPhone because of the camera, bluetooth, and built-in earphone and transmitter. I was using Vonage Mobile (free unlimited domestic calls in the US--I have actually tethered it to the Treo Pro and gotten decent call quality at times!) for the iTouch and discovered that in order to activate the iPhone version, there was a test call that needed to go through, hence the goPhone SIM and the unlocking process.

Back to my problem. I have been unable to sync the device to iTunes and download my songs to the iPhone. It wants me to restore the phone and says that an iPhone (with my coworker's phone number) has already been synced to this computer. The reason I say my issue MAY be unique, is because most of the posters with unlocked iPhones seem to have "legit" AT&T iPhone accounts which is what I suspect may be my issue. My last resort, of course, is to restore the phone back to factory state, but I really don't want to lose my programs and such. I do have Pandora and Slacker, so I can listen to music most of the time, but I don't want to be restricted to wi-fi, since Edge is not really a practical option. ($20 for 100mb, and it is a pain to configure without a T-Mobile SIM card).

So, again, what I really want is to sync my jailbroken, unlocked iPhone 2G to iTunes.

Any suggestions?

Well, I don't think your issue is in regards to whether you have a "legit" AT&T account or not. I do think that maybe you do need to restore the phone. Usually a restore is much easier than trying to pinpoint a specific problem and fixing it if it isn't obvious to begin with. If you're concerned about your apps, such as Pandora and Slacker, you can just redownload them from the App Store. They're free, aren't they?

Thanks for the reply! No, it's the OTHER apps, particularly GV mobile. I know I can redownload them too, and probably will, but it's just the hassle. I'm working fulltime, and in school (should be studying right now--lol) and dont really want to waste the time. I wish it would just sync like its supposed to. There's got to be a way to delete some file from the registry (does mac even have a "registry") and have it work.

Thanks again...
