To all iPad2 64Gig WiFi owners. My IPad2 was working fine for a couple of months then as most described, I was getting like white noise, o no sound at all using Skype/FaceTime/Recording videos.
I checked online and went through the claim made by iLounge to its iPad 2 review on how the same microphone is placed in the two different models.
I found for my iPad2 64Gig WiFi (no 3G), the microphone was placed above the front camera (that tiny hole that I inspected when I got my iPad2 the first day and forgot to inspect later).
Well, I blew that whole with a Compressed Gas Duster (Dynex, part numer DX-CNDAIR1) and tested recording one more time.... Problem Solved!
I had opened online (earlier to my discovery) a support ticket with Apple, they will mail a box so I can send them my iPad for repair/replacement. I'll wait a few weeks before I release my iPad2 to them, as I have a custom engrave and don't like the idea to wait for 2-4 weeks to get the replacement back. I'll keep you posted!
