Ever since I moved to university, iTunes has given me an error every time I want to update my apps, and I guess whenever I try to buy apps too (though I haven't tried). I get the error, "The item you tried to buy is no longer available". Everything else works fine, so i don't know why this would be. EDIT: I just tried to buy an app and it did work (Soosiz), but updating still doesnt. EDIT 2: Ok false alarm, it was an error with Defender Chronicles 1.3, i could download all the other updates manually but the 'download all' button didn't work.
That's bad, i feel for you. Soosiz is really good thought and you could deleted the apps what need updating and download them again.
