i've heard such problem before. when your sometimes isn't strong enough, iphone will automatically began to utilized the 3G speed. the best way i guess should be stopping the 3G usage completely by stopping it inside iphone settings.

Switch off the Cellular Data, then it will only use the WiFi..

Ya, i checked already. The option is not for IPhone. That's why asking here.
And even it allowed, does local telco recognize the protection plan?

Switch off both cellular data & 3G

AT&T iPhone 3GS cannot be activated with Universal Simcard.
Is the above statement true?

I heard they have recently updated their carrier or something. So only AT&T Sim card would work.

Yes it is very true. You can close tread in less than a min.

Expired AT&T simcard can work or not?
