And don't forget its 21Mbps ONLY on the cities that TMobile may have 3G in, I waited 2 years for 3G to exist on the TMobile network before I switched to ATT and I haven't looked back. I believe the statement would hold more water if TMobile. Making a statement is one thing, making it happen is a very different one.
HSPA+ in 2010, translates to maybe ONE city having it on Dec 31st, 2010. You can't trust anything TMobile says.
