So two weeks ago I sold my iPad 3 retina to a friend of mine and picked up a new sealed in box iPad Air off of Craigslist. Got it for $460US thinking it was a 16gig wifi. Got it home opened it up and it's a sprint LTE model (BONUS!). So I power it up and it's already got a sprint SIM card and it's already on a 25MB data plan. So I talk to the seller and we figure out I just need to eject the sim and I'll be set. Btw the seller has a business account with sprint and has to order more than he needs. So my question is: can I take this to another carrier? I know these iPads are technically "unlocked". I usually just tether to my iPhone but I might like having a very small data plan to use in a pinch and be able to use the find my iPhone tracking.
