It seems this question would have already been asked, but a forum search didn't find much. This may be a stupid question, but AT&T typically has updated it's networks with each iPhone roll out. It seems Apple and AT&T alays work it out where the iPhone will always be using the latest network as soon as it becomes available. 2007: Just before the original iPhone launch EDGE speeds were boosted from ~120kbps to ~200kbps 2008: When the iPhone 3g Launched AT&T made a big push to get 3g into more areas, (areas that already had 3g got a bump from 1.6mbps to 3.2 mbps?) 2009: When the 3gs Launched AT&T was rolling out 850mhz and 7mbps 3G 2010: When the new iPhone launches AT&T will be rolling out 14mbps 3g HSPA+ It only seems the new iPhone would have this ability.
