Wireless will NOT Turn On? My phone until today worked fine, however, now the Wi-Fi on my GTi9300 will not Turn on. When I try to do this via settings the message I get says "Turning on...." and will not go further. I have tried removing the battery and switching on again, and this makes no difference to the message I get. How can I resolve this issue, as the wireless mode is what I use 99% of the time??
