Hey, I have a T-Mobile iPad Air I received as a gift last year and I wanted to sell it. The question is: is the iPad locked? My brother bought it for me to build his credit but we have not finished paying it off. I plan on paying it off once I sell it. Is it possible to sell it this way? Are iPads unlocked? I want an iPad Air 2, but I have no use for LTE since I have an iPhone and can easily tether. I've looked online but I get mixed replies. If anyone could help, I'd greatly appreciate it. Thank you.
