iPhone 3G iOS 4.2.1 wifi problem (Wifi Icon dissapear on status bar!)
I'm wondering if all the iOS 4.2.1 users out there have the same problem I have been having. If I lock the screen I can see i'm connected and the wifi icon shows on the status bar. Once I enter my passcode to unlock the screen the wifi icon would disappear but when I go to wifi on the phone it shows it's connected but the wifi icon disappear from the status bar. Any have this problem? Even tho, it shows it's connected to the wifi it doesn't seem to have the wifi speed. :confused: I tried resetting router, renew ip, reset network settings on iPhone nothing works. The wifi is connected but the wifi icon would still disappear from the status bar! Please help me. If there are no solution I will probably downgrade back to 3.1.2-3.1.3. Thanks for any help.
