update ipad on someone else's computer
My niece has an ipad 2 with ios 4.3.3. she doesnt have a computer. how can she update her ipad on my computer? we tried on my computer in my itunes. itunes identifies her ipad, but then suggests backing things up because they will be lost during the update. it also suggests doing the update on the computer/itunes the was originally used. But im not sure she ever did that. that is why she has ios 4 and not 5 or 6. How can we do this?
thank you
