The AT&T network is about to get faster. Twice as fast as current 3G speeds, using HSPA 7.2 3G wireless technology. This in-progress upgrade to the AT&T network will make speeds of up to 7.2 Mbps possible later this year.
Apple has reportedly designed the next generation iPhone 3.0 to take advantage of these network upgrades when it is released this summer, making the new device twice as fast as current models. LTE technology, otherwise known as 4G, is in the works for future upgrades at AT&T but won't be widely available until 2011.
