At work we have a Samsung Moment on loan from Sprint for Testing. I'm checking to see if it will be an acceptable replacement for my Blackberry 8330. So far it looks like it will do everything I need and more.
I started the Last.FM app just for fun and up comes a AT&T 3G network ad.
This is pretty funny because I had a AT&T 3G card and plan before switching to Sprint 3G through work.
On AT&T would regularly get 3-5Mbps in Milwaukee, Minneapolis, and Salt Lake City.
Service anywhere in-between? EDG/GPRS at 128Kbps. On Sprint I get 3Mbps to 400Kbps in most areas.
This is not to say Sprint is perfect. So far as pure coverage my AT&T card worked everywhere. I know of several areas where I have no Sprint voice or data coverage and I have OK AT&T voice coverage and low speed data. The difference is I can drive 5 minutes to leave the dead zone to get 3G speeds on Sprint. I have to travel to a major metro to get 3G on AT&T.
Verizon's depiction of AT&T's 3G coverage matches my experience. ¶ 12:48 PM
