I don't know how T-Mobile is in my area. Is it true they don't have a 3G network? If so, Google is being lame going with them rather than Verizon. I want the Android 2.1. When will the Droid get the update?
T-Mobile has a 3G network, it just runs on obscure 3G bands (the 1700MHz band for downstream and the 1900MHz band for upstream). T-Mobile claims it allows for faster downloads, but that's all not realistic in real tests. AT&T uses the 850MHz band for downstream and the 1900MHz band for upstream. 2G is completely compatible with both networks, but 3G will only work on T-Mobile's network.
I am not considering this in the least. I'd rather die than be put through another crappy network. (AT&T was my first, and last.)
