Well, ATT's network capability, or lack there of on the 7.2 HSPA front is irrelevant to Apple.
And your post is irrelevant to this thread, in which the OP was pondering whether it would be worth it for him to upgrade his 3g for use on ATTM (an assumption I made from his listed location and the general tenor of his comments).
Unless my assumption that he is on ATTM is incorrect, the ability of the device to make use of 7.2 HSPA on ATTM's network certainly would be a factor is his determining whether it would be worth it for him to upgrade.
