So, I powered my iPhone on tonight about five minutes ago after just syncing it with iTunes and I go into settings, and underneath WiFi, I see a "Carrier" menu. I'll select it, and it will move onto the next screen, and just now, I have a choice between Automatic, AT&T, and AT&T (????). Has anybody else noticed this? I searched and got nothing. I'm running a virgin 1.1.2 build 3B48b.
