Today at brunch I gave my mother a new iPad for her birthday, Wi-Fi only, which I was able to pick up from the local Best Buy Mobile store. Upon registering and starting it up at her house, my mother called and asked me why it was displaying the AT&T name in the top left corner. Does anyone know why this may be occurring? I thought the Wi-Fi only models had no ability to detect the AT&T (or Verizon) network. Did Best Buy give me the wrong model?
