Please help me. I just bought n80 black with this version... now "N80 Version 5.0719.0.2 RM-92 N80(01) ", im having trouble with my SUN sim signal... sometimes it goes up and down, but mostly it doesnt have signal.. but no problem at all when using my GLOBE sim...it has full signal strength.. i also tried turning to gsm,dual,umts and stil having problem.. is it my firmware? or someone just tripped and broke some ic on the phones? can you give me some advice? if its the firmware? how to reset it back to old one? thanks in advance.

No, there's no problem to ur firmware or any other prob involving ur fon.. Its just that the signal of Sun Cellular here in the Phils. is weak unlike Smart and Globe.. ayt??
