Forgive my ignorance but can I buy an unlocked iPad Mini? I plan to buy one for my Mom for her to use in the Philippines. I was confused by the Apple store when the selections are only with carrier iPad Mini, does that mean I have to commit to the carriers when I buy one? Does it matter which carrier iPad mini I buy when I'm hoping to use one of the carriers in the Philippines instead? Please advise. Any help or suggestions will be greatly appreciated. Thanks.
