Having other problems now. Im new
to itunes, iphone etc.
I originally synced my new iphone to itunes on my laptop with all my songs.
Due to HDD size issues I wanted to download Batman begins and a music album. So i use my desktop machine which has my step daughters ipod synced to. I download the stuff and now i cannot sync without erasing my iphone! I realise because of piracy this issue exists but I have logged in in my apple id and i cannot put it on my own iphone, crazy!
Anyone know a solution?
Can i copy these purchses over to my laptop and sync there?
