The T-mobile Pulse mini was announced at the Mobile World Congress 2010 (MWC 2010) in February where there are a few videos shot showing the handset hands on in action. A few specs include include a 2.8-inch QVGA screen, stylus for the resistive screen, 3.2 megapixel camera, HSDPA, Wi-Fi b/g and a personalized UI which has some awesome widgets and scrolling features. But according to news site ElectricPig there is NO GPS, potentially to reduce overall cost but if correct, you could kick all the those location based apps out the window.
T-mobiles Pulse Mini is the big brother of T-mobiles other Android powered handset; the T-mobile Pulse. Two main differences between models are the Mini rolls with Android 2.1.
