I have an iPad 2.0 that i received at a conference and it is preloaded with a bunch of free apps. I would like to load the apps i have purchased on my iPad 1.0 onto this iPad and still retain the ones that are already loaded. I would also like to move over all my Calendar information. I will then erase everything off my iPad1 and give it to my son. How can i load apps from 2 itunes accounts onto my iPad?
