I had to do a restore on my 3G IPad yesterday after the genius bar ran their diagnostics program. This got me to thinking.. We are taking our RV on the road for a couple of months. I got the IPad for the ease of reading publications that I can download. It's my understanding that you can only have your IPad/IPhone tied to one computer. If my IPad needs to be restored again while on the road, how do I address this issue with my desktop computer back home? Can I download Itunes to my laptop and sync with it while on the road and then sync with the main computer when I get home? Thanks.
