Well my Internet went down for 5 minutes recently, came back on and everything worked again (PC, consoles, mum's and dad's iPhones, etc.) however my 3GS didn't. It's connected to the Internet but when I try to do anything it just says it's not connected. 
I've restored, forgot the network, joined it again and still nothing. What's going on?
Thanks.
