I'm looking to buy an iPad off ebay, and it's locked to At&T. I just want an iPad that I can use wifi on, since I'm going to Hong Kong in a couple of months and want to use free wifi instead of having to pay for a data plan that won't work there.
Will an iPad being locked to a certain carrier affect my ability to use it at all, or do I have to make sure to unlock it when I get it?
