suddenly bars which shows the anten dissapear,then when I search as manuel doesnt find,like I am out of districkt,when I turn off and turn it on again the phone,then bars are full again!! 2 times it happened to me

i guess u r talking about the network signal bar? this morning when i 1st turn on my phone, 1st time encountered the same problem after having the phone for 2 weeks. Restart the phone and the bar came back full again. Don't know who else having the same problem. I guess this issues same as the 8310 that I previously own but after upgrading the firmware the problem gone.

I have the same problem in Singapore. Operator is M1.
I have to turn off the phone to get back the bar. I have the phone for
3 weeks now, happen to me a few times already.

Report this to Nokia. If they don't know about this problem, then they may not have the fix.

thanks for the mail!! what software U have?there is already new software update!!

I have V 3.12
