we need to know what settings were changed first..

This shall work... if not, i remember reading bout tapping that simcard....

I also got this problem on my iphone 3g.
this how i fix. i use digi.

1. remove sim card on iphone.
2. try use ur simcard on other phone to search network (if u see signal strength)
3. try put back ur simcard on ur iphone.
4. it works for me.

but the problem not stop there.
i still got the problem when i go to place where no digi coverage for a minute.
then its happen again. signal carrier "network lost". "no service" display.
i have to redo above step again to getting signal digi works.

i'm still searching the best solution.

any help?

pity ehh.. does urs the unlocked from apple or u do unlocking/ jb etc?

First, did u unlock using sim proxy ? If yes, than it's normal to happen like that. That is why, unlock iphone 3G using sim proxy like turbo sim, simpsons, simulator bla...bla is not total solution for unlock iphone 3G

fyi, my iphone now cannot have maxis simcard in it. network lost. but its work find for celcom. anyone can help me. i though my simcard problem, but try other maxis simcard also the same.
