Last night i was texting wid my frnd. Suddenly my phone turned off..I turned it on again but it came till the home screen and turned off again.I tried it again but the result is same.I removed the sim card and tried. This time it is working fine without sim card in it.I tried with different simcard but it is not working...I even tried by putting my phone in flight mode , turning it off and again switching on with sim card in it and flight mode..It started fine but when i put my mobile in normL mode and as soon as it starts searching for signal, it again turned off.... so sony please help mee .. is it a hardware problem or jst a software one....??
