        Thuraya recently released a phone combining satellite, tri-band GSM, and GPS functionality. The six-ounce, Windows CE-powered SG-2520 makes ordinary cellular calls when it can get a signal, and automatically switches to satellite calling at other times, the company says.

        Unlike satellite phones of yore, the SG-2520 looks and acts like a normal cell phone. Thuraya says that whichever network is being employed (cellular or satellite), users can browse the Web on the device's 1.9-inch display, send and receive email, and access SMS or MMS text messaging.

        The SG-2520 employs Thuraya's Geo Mobile Packet Radio Service (GmPRS), claimed to be TCP/IP-compatible and to provide "always on" connectivity. Data transfer is rated at up to 60 Kbps via GmPRS and 85.6 Kbps via GSM.

        Also included in the phone is a SiRF starIII GPS receiver. This is said to make the phone useful both as a navigational device and for position reporting.

        Finally, the SG-2520 also includes a 1.3 megapixel camera, capable of shooting still pictures and taking video clips. Thuraya claims this is the first device that lets users email images instantly even from remote areas.
        Specifications include:
        • Processor -- not specified

        Thuraya said in a statement that it plans to sell at least 70,000 units of the SG-2520 by next March. The company claims its satellite-only SO-2510, launched in 2006, to be a "runaway success," with sales of more than 60,000 units in just four months.

        The SG-2520 is available now, priced at $1,095 in the U.S.
