Would You Prefer Your T-Mobile Data Delivered Fast or Sometimes Slow?
This comes on the heels of T-Mobile unveiling plans in March of 2010 to upgrade its national high-speed 3G service to the High-Speed Packet Access Plus (HSPA+) technology, which will deliver customers data speeds faster than the current 3G network technology. By the end of 2010, T-Mobile expects to have HSPA+ deployed across the breadth of its 3G footprint, covering more than 100 metropolitan areas and 185 million people.
How ironic, with AT&T, the slowdowns come for free on the iPhone everywhere and it doesn't matter what the bandwidth usage is :).
