I saw this question asked earlier and didn't see a good enough answer so I am posting same question. To clarify, I owned a Wifi version of iPad for a month, now have my 3G model. i want to take all the data on my wifi model and move it over to the 3G.. and yes, I will obviously sell the wifi model once I have done this. The issue is moving the data. I do not want to risk a restore because I think the 3G has different software for the 3G parts, so if I try a full restore won't this break? My guess is I have to plug it in as new and it will sync the apps but I'll have to tansfer manually any data between apps? Or does the restore of backed up info not touch the iPad OS?
