Hi,
First try to Soft reset the Phone anf if doesnt wotk try Hard reset and if it still doesnt try upgrading the software, and if it still doesnt work you have to take it to service center..
The procedure for the above said thigs are said below:
For soft reset, just insert the stylus in the hole on the bottom left
For Hard reset,Try to remove the battery and keep it off for some 20-40 minutes, to let the device hard reset. Then, insert it again. At the initial phase, the device should spend some minutes installing some pre-loaded applications. You will see messages flashing in the screen. Do not turn it off at this time.
Try running the i-mate ROM upgrade downloadable here:

2. Extract the contents of the above mentioned rom to the memory card
3. Remove the simcard, insert the memory card back and then insert the battery
