It looks like Motorola are pushing out a few new mobile phones in the low end range for emerging markets with the model prefix WX according to an article over on engadget mobile.
The Motorola WX series will be pretty basic stuff such as small displays, GMS/GPRS and possibly EDGE, optional Bluetooth, a VGA camera or maybe none at all and either minimal or no internal storage.
The word is when the Motorola WX series hits it will probably go for about $20, and the one we are hearing about at the moment is the Motorola WX395 which is as basic as it comes with just GPRS; more as and when we know.
