IPhone 4 won't hold WiFi or 3G connections
Over the last 48 hours I've noticed that my iPhone 4 with 4.3.3 keeps losing both WiFi & 3G settings all the time.
I can force the WiFi back if I go to my carrier settings and simply ask it to search for available carriers (no idea why this fixes WiFi as it isn't helping to restore 3G!).
If I do this I get WiFi back for maybe 20 seconds before it drops again.
If I power down and back up again I seem to get WiFi for a longer time but still get issues with 3G.
Any ideas anyone?
