    Understanding network bands and frequencies for a GSM/UMTS phone
    The network bands and frequencies available for your webOS phone are listed below.

    Region ....................................... 2G frequencies ......................... 3G frequencies
    North America (US/CAN) ............. 850/900/1800/1900 GSM ................. 850/1900/2100 UMTS
    South America (LAT) .................. 850/900/1800/1900 GSM ................. 850/900/2100 UMTS
    Asia-Pacific .......................................... 1900/1800 GSM ................. 850/900/2100 UMTS
    Europe .................... 850/900/1800 /1900 (degraded) GSM ................. 900/2100 UMTS

    Europe uses 900/2100 UMTS for 3G data, North America uses 850/1900/2100 UMTS for 3G data.

    Specifications for the Palm Pre device: Quad-Band GSM/Edge and Dual Band UTMS 3G

    Furthermore, disassembly of both the EU Pre and the Telcel Mexico Palm Pre uncovered TWO different communication boards.
    The EU Palm Pre contains a board marked "EU" whilst the Telcel Mexico Palm Pre contains a board marked "NA".

    Europe uses 900/2100 UMTS for 3G data, North America uses 850/1900/2100 UMTS for 3G data.

    Does this mean you cán buy a palm Pre Plus in USA and use it on 3G in europe (because both uses 2100 UMTS? Or are those different chips/configs?

    No, because the Pre and Pixi have "Dual Band" 3G UTMS/HSDPA radios.

    North American radio board used in the Telcel Pre and AT&T Pre Plus is 850/1900
    EU radio board used in "WR" Pre's is 900/2100 UTMS/HSDPA

    Yes, 2100 UTMS is listed in North America, but T-Mobile USA uses the 2100 sprectrum for it's own flavor of 3G. Everyone else (Rogers/Fido, Telcel, AT&T) use 850/1900.

    Hope that helps.

    To make it even more complicated, T-mobile actually uses 1700 MHz and 2100 MHz spectrum for 3G called AWS. By the way, European 3G 2100 MHz phones are not compatible with AWS (Advanced Wireless Services - Wikipedia, the free encyclopedia).

    That Palm's list of frequencies is not quite correct.

    It would be much easier for everyone if Palm produced a quad band 3G device (like iphone for example) instead of having 2 versions, one for Europe and the other for GSM North America.
