Updating the OS on a Different Computer
My iPad is still running OS 3.2 and I want to update the OS. I don't have access to my own computer, so I want to update the OS using my sister's Mac. I've read everything I can find on this issue, and I am still confused.
I don't want to sync all my stuff to her Mac--I only want to update the OS.
I have downloaded many apps directly to my ipad via wifi, and these apps have never been synced to my own computer because i dont have access to it. If i am updating the OS using my sister,s Mac and a box appears that asks me if I want to "transfer purchases," should I check yes or no? If I check no, will my apps disappear from my iPad? I don't really want to transfer purchases to her computer, do I? Not sure what to do here...
Prior to updating the OS, should I make a "backup" on her computer in case something goes wrong?
I really hope someone can give me a little advice here. The more I google for answers the more confused I get! Thanks.
