[1.1.3][EDGE] Try to solve the problem here
i thought that it would be good to bring this point into a seperate thread, as many people in the other threads respond that you just have to reset the network settings - that's not the case.
So, let me explain the issue:
On 1.1.3 i believe Apple entered the right APN settings for the official providers, so T-Mobile Germany, AT&T USA, O2 UK - if you then use a card of this providers on an unlocked/jailbroken phone, you don't see the EDGE settings anymore (under General - Network). If you put in another card, you can see the menu.
So we need to find out a way to enable the EDGE settings again, so that users can enter the right APN settings.
I tested to edit the carrier.plist in the Unkown Folder, but that didn't had any positive impact.
I hope that one of the developers has an idea how to fix that.
