I just got an iPhone replacement less than 2 weeks ago. I synced it with my iTunes and most my stuff went on my new phone. However, every time I try to upgrade my apps it says that I can't upgrade unless I buy the original version, meanwhile, I already have it. So then I called and the lady told me to buy it anyway, and if they charged me for it, that Apple would refund it. Well after I hit "Buy" it says that I can't upgrade because the app is currently being modified and to try again later. Wtf?
