Up until today I have experienced no problems since jailbreaking my 3GS 2 days ago. Today I went to go online and realised that I wasn't connected to the household wireless network which I've had no problems with up until now. I double checked the router which is all in order, which it was. Next I checked that I was able to connect to the router using 2 different laptops in the house, which I could. No matter what I do the iphone doesn't pick up any wireless networks at all even when I'm sitting right next to the router?? I tried inputing the network login details manually Settings>Wireless>Other but I get a message saying the network can't be found. In place where the wireless signal strength icon usually is on the menu bar, is a circle which I've never seen before but that might just be because I've always used 3G and since Im on holiday overseas, I have switched 3G off.
