1. goto menu>settings>connectivity>mobile networks
2. change search mode instead of auto to manual
3. then choose select network, the fon will searching for any mobile network exists
4. choose any of the network except ur telco (if u use maxis, change to celcom or digi)
5. when it says forbidden network, choose yes
6. go to standby mode.. tadaa

at the operator logo will display select network?
at left softkey is ok, so dont press it
ur fon is in flightmode now, no one will disturb u anymore

actually i figure out this trick long time before, when i use t610..
i think other brands also can do like this oso, but i'm not sure, never tried before
