The HTC Sensation I'm using does PCS 3G on 900, 1700 and 2100, and EDGE on 850, 900, 1800 and 1900.
Looking at that wiki document again, it looks like you can operate GSM and UTMS on the same band. It seems they're doing it already in certain parts of the country.
I guess they're getting rid of GSM all together. Interesting.....
I need to read up more on how that works. I always thought the only way T-Mobile could offer simultaneous voice and data on a handset is by using GSM to place/receive calls and UTMS for data.
umts/hspa has always had the ability for calling & data at the same time. No 2g network technically needed and T-Mobile does have some he hspa only areas.--
