T-Mobile SDA

Brighthands has a review of the T-Mobile SDA smartphone, and talks about the phone’s WiFi features and VoIP: “The only real application I can think of for the SDA’s Wi-Fi is Voice-over-IP. And to be sure, this is a pretty compelling case. T-Mobile is supposed to be implementing Unlicensed Mobile Access sometime this year, a technology that allows for switching calls between GSM and VoIP networks. Even if this doesn’t come into play, the idea of being able to talk without burning up minutes, or in areas that don’t normally get coverage, is tempting. Such an ability also makes the SDA ideal for use in hospitals or other areas where typical cell phone transmissions might be frowned upon but lower-powered Wi-Fi networks would be acceptable. The SDA could function as both a conventional cell phone and an IP phone, minimizing the hurdles for a comfortable VoIP solution.”

In addition to WiFi, the T-Mobile SDA offers users the following features:

* display: 65k TFT, 176 x 220 pixels
* VGA camera
* Bluetooth
* tri-band GSM
* music player
* 64MB ROM
* 32MB RAM
* miniSD memory expansion slot
