just got off the phone with tmobile and the tech gave me this link: UNofficial, T-Mobile Vibrant update! - T-Mobile Community
seems to be quite a few fix's with this. will report back after applying this update (I know this is for the vibrant so I would NOT try this on other galaxy s variants if I were you. but it tmobile has this fix then maybe sprint and verizon are on the ball with this as well...give em a call!)
It sounds like more people are having this problem than not. However, I just spent over 28 hours in a plane and didn't have it happen once. I hate problems that affect some users and not others.
How did you guys transfer the music over? Just copy and paste? I use iSyncr.
