I took apart my new bsquare today to puts around and discovered that the GSM module is made by ubinetics in the UK. The module in the production version is the 900/1800mhz p/n: gm404. If we could get ahold of a 900/1900mhz p/n: gm405 and plug it in....maybe..... I emailed them about a source for these as they have been phased out. Still waiting for a reply. Will keep you posted!
