I suspect that this will not be a problem, but would like clarification that there won't be any problems syncing my old iPad information to a new iPad 2. Will the different versions of IOS (4.2 and 4.3) pose problems when restoring to the new device? I'd really rather not have to setup all of my preferences again from scratch. I don't think I've ever dealt with this scenario with my iPhones over the years. Insight will be appreciated, thanks.
