I recently jailbroke my iPhone 3gs with jailbreakme.
At the beginning everything was working well. But since yesterday I am having problems with the network. It would disconnect from wifi and there is no way that I can reconnect until I reboot my phone. It happened twice so far, but I am not able to reproduce the problem as it doesn't happen all the time.
Anyone here has any hint on what I should check?
Edit: I found out that this problem occurs if it changes wifi network.
Edit: Resetting the network settings was the right solution for me. Does anyone know if this is a common problem? ( I was not able to find anything with google )
