I did a search to see if anyone else was having issues with their WiFi. Since I upgraded my ihone4 and Ipad to 4.2, neither auto connect to Wifi if they have been turned off. You hve to go into settings and tap the router name to force connection. It's driving me quite mad. It didn't do this before the 4.2 upgrade. There's already been mention that multi tasking doesn't seem to work either. One wonders if anyone at Apple actually used the Ios before they released it. I can't believe the beta testers didn't notice it either? Am I doning something wrong now?
