Hello,

I have unlocked my iphone with anysim ibrickr etc, but I have two major problems:

1- I can use wifi, but after a minute or 2 wifi disconnects and the iphone keeps searching for a network. If I go to settings the phone finds no wifi networks (but there are). Only reboot works, but the problems keeps coming back.
My brother has an iphone too but he doesn't have this problem, so it is not network related

2- When I call someone I don't have audio, so i can't hear the other person...It only works when I switch to speaker and then switch back to normal. I have tried the trick of plugging in and out of the headset...

What could be the cause of these problems?? I have restored my iphone 4 times, but nothing seems to help..Right now i've totalled had with my iphone

Same problem here! Have you tried a Virgin full restore? Not the one in Itunes?
The solution is to do the virgin restore then Unlock your Iphone again. I havnt tryed it beacuse im not that good with hacking and stuff.
