Hi, Currenty own a 3G iPad. While its useful and handy, i've found myself not using it as much as I had when it was released. Im looking into selling it. However, i had once on it the plan with at&t for data. Obviously my account is tied to that microsim. Is it possible to get a new replacement microsim for free? Is apple or at&t giving out free microsims to customers? I'd like to put a fresh one in for the buyer before I sell it. Any suggestions would be appreciated?
