My keyboard takes 10 secs to type 1 letter. I have no sounds at all on any applications. IT&T appeared where the 02 carrier normally is - could this be the problem? Obviously I've checked the settings and all sound preferences are set. I switched the thing (iPhone) on and off. When I receive a call, the Answer/Decline option shows only when caller hangs up. It's just one hassle after another! I have trawled through various threads and see that the problem I have goes back to 2007. Am I being 'picky' thinking Apple should have sorted this rather than allow this annoying issue to be ongoing? I'm disappointed at having to pay a premium for a 'phone' which constantly causes grief.
