iPhone 4 issues I am experiencing

It appears I ran the gamut.
I bought two phones. One for my wife and one for myself to update our 3G phones.
Green Photos
My wifes takes noticeably better (but still green) photos than my iPhone. The entire photo is reddish with the center very green. We took comparison photos of the same subjects in the same environment for comparison. Very ugly and noticeable. The face cameras seem MUCH better on both. White objects look white only on the face camera. I cannot emphasize how green and red these images look. It is NOT a subtle thing.
Face detection too sensitive/or not sensitive enough?
Ive muted calls and even hung some up with my face even though I have it pressed against my ear. (I cant have a Blue-tooth earpiece on at all times at work.)
Dropped calls & bars
Left hand, bars drop within 15 seconds until the call is dropped. The only time it doesnt drop the calls is when we are in areas with really great reception. Otherwise at home, at work or on my commute I have to use the speakerphone and hold it with one hand so I cant browse or read e-mails or anything.
Compass Interference
This one doesnt worry me too much since the whole compass thing was more of a gimmick than anything useful. I often get that figure 8 to re-calibrate the compass while using the map.
