AT&T's 3G Overhaul
HSUPA enables uplink speeds of between 500 and 800 Kbit/s, along with the downlink speeds of 1.4 Mbit/s offered by the general high-speed packet upgrade. Uplink speeds are becoming increasingly important to operators, as users want to use their phones to show off photos, videos, and music.
The upgrade comes just in time for the unveiling of the 3G iPhone, which is expected on the morning of June 9th. AT&T currently covers 275 markets with the HSPA upgrade.
Of course, there're always faster uplinks out there. Consider Vodafone Group plc (NYSE: VOD)'s new broadband service in London with 1 Mbit/s throughput. (See Vodafone's Blazin' 3G Upgrade.)
