AT&T now claims to have 80% of their network with HSPA+ but they don't provide a coverage map yet. Also, AT&T does not tell you that your old phone and iPhone will not work on the HSPA+ network and you will be required to buy a new phone like the ones below that are AT&T 4G compatible. All of you iPhone lovers who just bought the iPhone 4 won't work on the faster AT&T's HSPDA network. The HTC Inspire sells for $499, Motorola ATRIX for $699 and the Samsung Infuse is $199. Very expensive if you ask me even with a data contract subsidy for $200 to $300. T-Mobile has had 4G HSPA+ for over a year and has a lot more phones to choose from if you plan to switch before the merger. Search Amazon.com for at&t 4g phones.
