T-Mobile's 3G service seems to be spreading (I see 3G in more areas) and getting a bit strong in my area. I see a 3G on my phone indoors more often than I did after its rollout here. My AT&T Wireless service was back for my iPhone and looked good downtown (-79 dBm). So, I decided to run a quick completely unscientific download speed test with my iPhone 3G (AT&T) and HTC TouchPro2 (T-Mobile).

I used DSLReports' non-Javascript dependent speedtest since Windows Mobile 6.1's web browser doesn't work with DSLReports more commonly used Javascript based speedtest...

I used a 1MB download payload for each test. Here's what I found based only a single test for each phone/carrier:

AT&T
iPhone 3G
613 Kbps
0.473 second latency

T-Mobile
HTC Touch Pro2
671 Kbps
0.539 second latency

I'm calling this a "tie". It surprised me since I thought I was seeing better throughput on the Touch Pro2. I should probably run more tests and in a variety of areas (including outdoors) to get a better picture of my local 3G situation.
