for what its worth, at the apple store when i bought ipad2 they did say to just backup 1 and restore to 2....but like i said not working for me. i suppose the jb might have something to do with it?
If you plug in your iPad1 are your backups listed for it? My guess is that they are. I still think this is a bad idea, but here are Apple's instructions....
1. Backup Your Old iPad
The first step in migrating is to back up your original iPad. To do this, simply plug it into your computer. If iTunes doesn't launch automatically, launch iTunes and then sync your iPad. Additionally, you can choose not to sync, but only
back up by right-clicking on the iPad in iTunes and choosing Back Up from the contextual menu.
So if you do this, do you now see your backup listed?
This backup is important - it will preserve your iPad's settings and saved data. It will not, however, back up your installed applications, music, movies, or photos. This must be done by syncing the iPad later in the process.
2. Prepare Your New iPad
This is the easiest step. Simply plugging it in to your computer and making sure iTunes is open will take care of it.
3. Restore.
With your iPad plugged in to your computer, within the iTunes interface, you should be presented with the option of setting up your iPad as a new device, or restoring from a backup. If for some reason you aren't presented with these options, then you can simply right-click (or option-click) your new iPad in iTunes, and select "restore from backup" in the contextual menu that follows.
iTunes will now make a copy of your backup, and use the copy to configure your new iPad with your old iPad's settings.
4. The First Sync: The Waiting Game
After the initial backup, your iPad will restart and begin syncing for the first time. It's important not to interrupt this, as iTunes is now migrating all your applications, music, movies, photos, and settings to the new iPad, carefully making sure to preserve their position on the home screen and in their respective folders. Interrupting the transfer might result in apps being out of place or content not being transferred to your new device.
