The modem used in the GTA04 is the Option GTM601W, which is a Quadband-GSM and Quadband-UMTS device. For UMTS, it fully supports Bands 1 (which is 2100 MHz) and Band 5 (which is 850 MHz), so it should support both bands your provider likely uses. As there doesn't seem to be any official public information about the device anymore, here's a link to a 3rd party detail list: http://m2msupport.net/m2msupport/option-gtm601w-hsdpa-3g-module/ -- thomasg _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
