I was unable to test upload and download speeds as there is no Windows Phone 7 Ookla app available yet (for measuring network speeds). I did some casual speed tests over Wi-Fi and found the browser paired with the 1GHz processor to be pretty speedy. PCWorld.com fully loaded in 22 seconds, media-heavy site Thrashermagazine.com loaded in 35 seconds and NYTimes.com loaded in 16.2 seconds.

One annoying issue I ran into was when I tried to sync my Facebook profile to the HD7. I'm not sure if this was a network issue or a problem with the operating system. It took about four tries to get my Facebook profile up-and-running. I also noticed that the phone seemed to switch between EDGE and 3G pretty frequently around San Francisco.

Call quality was hit-or-miss over T-Mobile's 3G network. Callers sounded good, but slightly distant and a bit tinny. On a busy city street, my caller on the other end of the line had a difficult time hearing my voice.

Conclusion

The HD7 is a high quality phone but without a front-facing camera or 4G data speeds, it can't compete with the , Apple iPhone 4, HTC EVO 4G or Samsung Epic 4G, which dominate the top spots on our . If you're a T-Mobile customer longing for a Windows Phone 7, however, the HTC HD7 is a nice introduction to the platform and a great entertainment phone. Make sure you give Windows Phone 7 a test run, however, before purchasing. It has a few quirks as well as a few missing features, like copy/paste and Flash support.
