I think your phone is SIM lock to be able to make it open line and to use other sim network bring it to a reliable cellphone technician they have the necessary tools and skills on how to unlock and make your phone open line..

Wifi on iphone 3g is not picking up wifi signal

it may be finding it but not showing the passcode screen to enter your wep key.
tap the wifi settings and set you network information and the wep network key which is located on your router.
If you put any other code in your wifi won;t connect.

IPhone EDGE issue

Access to edge or other data services depend on the isp, not the cell phone manufacturer. For example, if you unlocked your phone and put a tmobile sim in it, you would have to get data settings from tmobile to be able to get the internet. You need to talk to the tech support people. And of course you can use the wifi on the apple phone for internet access.
