I wonder if many people are having problems with the microphone? My new ipad (white 64 3G) worked fine for a day or two, and subsequently only records a sort of static noise. After resetting, and installing the new firmware, the problem persisted - so I returned to the apple store. They exchanged it straight away (the guy didnt even turn it on, and luckily they had another in the back) however the new device has a fair bit more 'light leakage' than the old! Seems I can't win.
