So this trend has been typical for the recent BlackBerry's...for example xx10 would include GPS, xx20 would include Wi-Fi, and xx30 is the CDMA version of the phone...but the thing is, the Curve 8900 includes both GPS and Wi-Fi. Then would it break the trend of having a possible 8910 and 8920??
Since wifi and GPS are built in the xx10 and xx20 designations are no longer relevant. I am sure the CDMA version will use 8930 though. And it looks like xx20 and xx10 will continue to be used in the pearl flip and storm lines.
I'd expect the 3g Curve II to be in the 9xxx series too. Maybe a 9300? 9220 seems like it would be taken by the forthcoming 3g pearl flip.
