Folks, If I buy an unlocked iPhone from somebody apart from AT&T will they sell me a micro sim and let me use on their network? Just want to check before I pull the trigger? Also is anybody using the Verizon iPhone and regularly moving between the iPhone and another device like a blackberry or a dried device? I think you dial *228 to switch. Just intrested to hear the experience you are getting. I need to move between devices so just trying to work out what is the easiest method... Swap the sim card or the verizon route. Thanks!
