I've read conflicting reports on these forums and elsewhere on what to do when selling an iPad with cellular. I have an iPad 3rd Gen (Verizon) that I just sold on eBay, and I'm unsure whether to leave the SIM card in the iPad. It's a pre-paid SIM that came in the iPad when I bought it. The account has been canceled and it's not tied to my post-paid iPhone account in any way. Take it out and be safe, or leave it in as an added convenience for the buyer if there's no risk of it being tied to my account or credit card in any way?
