So I decided to try restoring my iPad to its unjailbroken status, so I put it into DFU mode and reset it to factory settings. But apparently I screwed up -- iTunes only keeps one iPad backup, and the one it has is from a post-jailbreak sync. On a whim I'm trying to restore to that backup, but it seems to be hanging on the "estimating time remaining" popup (it's been there for about half an hour now). All I want on the iPad is my legitimate and official apps, etc. Is this normal? If not, how can I rectify the problem? Is it that I'm trying to restore from a post-jailbreak backup? If I choose just to set up the iPad as a new device, then sync it with my library, will I lose my incremental data (comics in Comiczeal 4, documents I've written in Pages, etc)?
