Yes, I discovered over the weekend that the internal microphone had stopped working so today it went back from whence it came.....PCWorld!
The mic was deffo working when I first got the IPad. Since then I have added a few apps and 'upgraded' from Ios 4.3.1 to 4.3.3. So...is it a op system glitch or shoddy components? Looking around on the net my money is on the OS, anyway I will be without my IPad 2 for seven to ten days according to the nice man in PCWorld.
