    Why no support for 1700/2100 bands

    Why no support for newer phones for T-mobile 3G US? No HTC Desire, No Dell Streak, No Droid 2 (GSM Flavor), Dell (2011 Lineup), HTC Desire, HTC Legend and more to come?

    Is it just because no one else in the world uses the 1700 band?

    Thanks

    1) It's not 1700/2100, just "UMTS1700", "UMTS Band IV", or more often "AWS". Yes, it uses some 2100MHz frequency, but calling it 1700/2100 is improper, misleading, confusing and incorrect per the GSMA and FCC. AWS is not compatible with UMTS Band I @ 2100MHz. It's like call PCS/UMTS1900 1800/1900, which suggests it's compatible with UMTS 1800, which it also is not. http://en.wikipedia.org/wiki/UMTS_frequency_bands
    2) AWS is used in the Americas. T-Mobile was just the first to use not, but not the only one.
    3) A version of the Dell Streak passed through the FCC with UMTS1700 support. SRC: http://androidandme.com/2010/02/news...-aka-t-mobile/

    The new Moto Milestone supports AWS.

    The primary reason AWS isn't as ubiquitous as Band II (PCS/1900) is because its deployment is relatively new compared to the other frequencies. The only UMTS 3g operators that use it are T-Mobile USA and Wind in Canada. That said, the number of devices that are coming out which support AWS is increasing at a pretty steady rate. As was mentioned, the Dell Streak also comes in a UMTS flavor. And frankly, a number of the devices you mentioned are Euro only and either don't support America at all (dual-band UMTS) or only support Band II in the US, making it good for roaming but bad for day-to-day use on ATT/Bellus/Rogers.

    The Legend and Desire are Euro-only phones. The counterpart to the Desire is of course the Nexus One. The Legend has no American counterpart.

    True. UMTS 1700 or AWS is not compatible with UMTS 2100. Its not the same. However, T-Mo phones, especially by HTC and Blackberry, do have a _separate_, _second_ and _true_ 2100 UMTS option for global roaming.

    Thus, an HTC Legend and Desire will only work on the US T-Mobile on EDGE. But a T-Mo Nexus One, MyTouch 3G, and even the new Slide will work in Asia and Europe in full 3G glory.

    Adoption of AWS has been slow because it's the newest 3G frequency, and in North America the only carrier to use it is T-Mobile, the smallest of the Tier 1 carriers.

    technically, there are a number of other carriers which use the AWS Band.
    Wind in Canada has a UMTS network.
    MetroPCS CDMA
    Cricket CDMA
    iWireless is rolling out their UMTS network
