Yeah a lot of my family/people I know are talking about Tmobile's increased 3G speeds... I think they're going to beat everyone to the "higher speed" market. I'm even tempted to get a Mytouch 4G...
may want to look into this a little more. T-Mobile is using HSPA+ which max download is 42mb/sec and verizon is using LTE which max download is 300mb/sec.
These wont be real world speeds but the possibility with optimal conditions is there.
