i successfully unlocked my iphone and it is currently running on tmobile. i did it by using the gui and i noticed that i can't transfer any songs to the ipod. i first used itunes 7.3 than i thought it might have been the software, so i updated to 7.4 and it is still not letting me drag music files to my iphone even after converting to acc. anybody know the work around for this problem? i tried it on both mac and windows. please somebody help me.
