[Resolved]  Sony Ericsson F305 — phone doesnt dectect the presence of sim...................

I too have a problem. It doesn't recieve calls if left unused for some time say 4 to 5 hours. This problem persist mostly In the mornings becuase the phone is not used at nights. Service centere Kizer electronics reloaded the software but still the problem persist. Now they say I need to leave the phone for 10 to 15 days to send it to the company. How will I manage without phone in this period. Wrote to company but no resposnse from them.
