I'm using iPhone 4 (IOS 4.1) for less than a month, and it's already disappointing me. When I call someone, I can hear them, but they cannot hear me unless I put them on loudspeaker, voice control can’t detect anything and voice memo's just pick up an annoying buzz sound...

I've made a full restore and problem still exist..

I've used iphone 2G, 3 years ago and I'm really happy about it. Then I switched to 3G and within first 6 month I’ve RMA my phone twice but still it gives me 2 'amazing' years. And now the 4th gen, I think quality control were more worsen
