My New Capacitive Touchscreen phone

Last week/year, I started looking out for a new capacitive touch screen, 3G mobile phone after my jailbroken(rooted), unlocked iPhone started loosing battery. Came across this device, a factory unlocked phone with most of the features I was looking for below INR Rs 10,000/- called Spice MI 300.



This device turned out to be a good phone with 3.2 inch WVGA capacitive touchscreen, GPS/AGPS, Gsensor ,a decent CPU qualcomm MSM 7227 ARMv6 running at 600MHZ, with a 2GB MicroSD (upgradable to 32GB) 156MB user phone memory, 256MB RAM, 512MB ROM, hardware capable of FM radio( SOC USI WM-BG-BM-02  need to verify), with a 1230mAH battery and a 5 Megapixel camera, Optical trackball, E-compass, Proximity Sensor, bluetooth 2.0 with A2DP + EDR, Wifi 802.11 b/g, GPRS | EDGE | 7.2Mbps HSDPA.

This phone is powered by modified version of linux 2.6 kernel. This mobile operating system is called Android which has an application platform running on a java stack,. The stock MI 300 runs (donut)Android 1.6 with an upgradable option of the firmware to (Eclair)Android 2.1.
I had earlier played with montavista linux runnning 2.4 kernel on a motorola A780 which had a resistive touch screen and also a keypad.

The first thing I do when I get any device is, try to dissassemble and see what goes inside the device. Warranty doesnot mean much these days. Before starting I searched around the net for any tips. It turned out that this device is a widely popular phone and has a 14 variants/clones with the same hardware under the hud manufactured by commtiva. Some of these clones are factory unlocked and some are tied to carriers which can be easily unlocked.

The combo Bluetooth/WIFI/SIP mobule USI WM-BG-AQ-02  spec pdf file and USI WM-BG-AQ-02 description. Looks like the hardware doesnot support FM Receiver :(
