It has been only 3 months since Sony Ericsson P900 is released to the public, but it has quickly become the favourite smart phone platform for many mobile developers. Reasons? Crystal clear 208x253 screen with 16-bit color depth (65k color), VGA Camera, touch screen and loaded with powerful Symbian OS 7.0. And last but not the least, very cool metalic outlook. But what does it has for us, the J2ME Developer communities? There is: the long waited MIDP 2.0 and Bluetooth API. In this review, I will take our reader into the nuts and bots of this phone.
