Cannot slide to answer phone calls
Some observations:
Currently have a 3GS but had same problem on a 3G.
Been through various OS updates with same problem IOS3 IOS4.
Only happens when trying to answer phone "Slide to unlock" always works.
Pressing menu button or turning silent button on/off a few times seems to help but shouldn't need to do this.
Have read other posts about resetting phone and ringtones but only use standard ringtone.
Any ideas?
3GS, iOS 4
