AT&T quickly shot back after news of the Verizon iPhone. The carrier simply touched on the strong points inherent to a GSM phone. An official statement pointed out that 7.2Mbps HSPA 3G was faster than 3.1Mbps EVDO Revision A and wouldn't be interrupted by calls, as is the case on CDMA. Most international carriers' use of GSM also ruled out roaming in the majority of areas.
