I own a 32GB 3GS and it's started having a strange problem with the Wifi. Whenever I turn it on it manages to connect to my router with full signal strength however the icon in the status bar does not change to reflect a wifi connection it instead stays on '3G'. I've tried updating the firmware to 3.0.1 and it hasn't fixed it, I've also tried to forget the network and reconnect. It just will not seem to use the Wifi connection. Any suggestions? Thanks.
