I will be doing a switch. I should rephrase my thread title. When the iPhone supports 4G, T-Mobile says they're revamping their network to be compatible with iPhone's bands. ******* AT&T's high prices for my single line. It'll nice refreshing to join my family's family plan again for the reduced bill ad have unlimited 4G speeds. The only reason why I'm on AT&T is because I don't wat to use Edge on an unlocked iPhone.
