I have the same issue with syncing my phone to a new computer. The music I can put on no problem, but my issue is with my contacts. I only have the contacts on the phone (and the old computer, but its been dismantled), so if I hit 'sync contacts' on itunes on the new computer, will it update whats on the phone to the new computer or will it just erase everything on the phone (because there's nothing on the computer!)?
Also, I went to itunes and re-downloaded any apps I had bought, which is fine, but now if I sync them to the phone will it replace the information IN the apps? Such as a note taking app that I have, will all the notes still be there once I sync with the app on the new computer?
Thanks for the info! I know this is an old post, but when I googled my problem its the main thing that comes up! So I hope you guys are still able to help me.
