unable to get current location on SonyEricsson X10i

I am us开发者_JAVA技巧ing SonyEricsson X10i phone. I have developend an application that just shows the current location of a user. Now the problem is When i turn on my application it just keep searching. It is not showing anything. Even if i try to use built in navigation system it does not work. I have turned on GPS receiver. My firmware version is 1.6 and kernel version is 2.6. I am not sure but i came to know from some resource that 1.6 firmware does not support GPS. Let me know if someone knows the solution.

• Are you indoor or outdoor? GPS usually only works well outdoor.
• Do you have turned 'network' as a data source on in your location settings? Allowing triangulation/cell towers/wifi networks to get the location if GPS/satellite is not available.
