I've pwnaged my iphone which worked perfectly and now i tried to put my pwn on a second iphone. Everything seemed fine but now, as i tr to connect to a wlan it does not work.

It shows me that it's connected and then it disconnects and wan't even find the network no more.

Is this a known issue? Has it to do with pwn? Or might the wlan be broke?

What can i do? In my country the iphone is not available yet, so apple store wan't be a possibility....
