How to clone iPad 1 to other iPad 1
The easiest way to do this is to iTunes on your Mac or PC.

Broadley speaking, the steps would be:


Launch iTunes on your Mac or PC
Connect the first iPad to your computer
iTunes should recognise that your iPad is connected and will display an iPad icon
Click on the iPad icon and view the Summary screen
You'll see a Backups section. Click on the Backup now button to make a full backup of the iPad to your computer. This may take some time.
Once completed, connect the other iPad to your computer
Repeat Steps 3 &amp; 4 above
In the same Backups section, click on the Restore Backup... button
You'll now have the option to restore from the backup you just made to your other iPad. This also may take some time.
