Hi. My question is this. Can I use an iPad if I don't have a computer? I think it initially needs to be attached to a computer, but could I use for instance my sisters computer to first set it up then would I just be able to use the iPad itself for the Internet, downloading apps etc. without having a computer of my own? I live in the country and would be getting an iPad with 3G. I know this is probably a dumb question but I don't know much about it. Thanks
