A relative wants to buy my iPad since I'm getting the iPad 2. I was planning on selling it to gazelle, but she will give me the same price. I have the unlimited data plan, and I haven't received my iPad 2 yet. I've read conflicting information: some say keep the sim because it's tied to the unlimited data plan, and others say to just call at&t and have them transfer the plan to your new iPad (and new sim). Instead of waiting for my iPad 2 to show up in a few weeks, I would like to go ahead and sell the iPad to her with the original sim, erase all of the data and info, set it up as a new iPad for her and then transfer my unlimited plan to my new iPad 2 when it gets here. Can I do this? If so, do I need to have info like the IMEI number when I call to transfer? If not, can she get a sim like this http://www.amazon.com/AT-Sim-Card-B...WGMC/ref=sr_1_1?ie=UTF8&qid=1300153558&sr=8-1 And use it in the iPad? Thanks for any info.
