IF AT&T looses its exclusiveness here in the USA where is it gona go on other carriers? By "Other carriers" I mean T-Mobile. I mean how well is an "iPhone 3G" going to market on a carrier that can't currently provide 3G bands that the iPhone supports? Look at it this way the only frequency's T-Mobile has allocated are 1900MHz and 2100MHz (US type so 2100 for download and 1700 for up) 1900 is for there EDGE and GPRS services and 2100MHz is for there UMTS services (3G). The iPhone currently does NOT support 1700MHz which is why the iPhone 3G can't get 3G service on T-Mobile at least in the US. This leads me to believe that its not too likely that the iPhone will be a big deal on T-Mobile and will probably not be encouraged by the carrier. I mean unless apple throws in a 1700MHz radio into there design it just seams like something that won't happen. Of course once AT&T looses its exclusiveness they might just sell unlocked phones and you could pop in a T-Mobile sim but still...Discuss I want to hear some thoughts..
