is it not possible to alter the computer it's registered to? My workmate gave me his old iPod Touch for £20 because he's just bought an iPhone, but I can't seem to get my macbook to register that it even exists. Any tips/tricks? The guy is sound and said if I couldn't get it to work I could get my money back, but I'd rather have mobile internet joy and a proper mp3 player. Should I take it to the regent street apple store and ask the boys there?
