need to sync my ipad without deleting apps.
ok, so i've been put in chrage of updating my moms iPad. so i plugged it into her comp and ran iTunes, thinking it'd be easy. apparently not. it gave me the standard "this iPad can only be synced with one library" message, even though I'm signed into her account on her computer, which is authorized for her itunes account. the only thing I can think of, is maybe the iPad is synced to her old windows laptop, and now it doesnt want to sync with the mac one.
my dilemma is, I dont want to sync with the newer computer if it means that will delete the angry birds saves on the ipad, which my younger brother has spent probably weeks of his life building up. if i do that everyone will be livid. so, how do I fix? i'm about to update iTunes and see if its just a bug, but im wondering if that doesnt work, would I be able to reinstall iTunes on the old computer and set it up, so that the apps may update to that one, then see if there's a way to transfer an iTunes backup from one computer to the next?
*hates the iTunes sync cartel* if the above doesn't work, would there be any chance this could be fixed when iOS 5 comes out, assuming i refuse the 4.3.3 update now and wait? the iPad is on 4.2.1 at the moment, by the way.
