So this might sound like a dumb question but I'm a little unsure on what I need to do. I purchased a black iPad 2 32gb 3G AT&T Best Buy. I decided that I really no longer need the 3g (just one more thing to pay for) and that a plain wifi one will be fine. So I've decided to sell the 3G model, but wasn't sure what I need to do before handing over the ipad to whoever buys it? Do I just hand it off to them and they can set it up on their own line? Or do I have to cancel the line that is connected to the iPad? Just wasn't sure what steps I need to take for it to be a "clean slate" for them to set up on their own AT&T account. Any help would be greatly appreciated. Thanks.
