Week 31, 32gb. Bought this past Friday. I can replicate the death grip problems if I try, but so far it has not affected me in actual use. No other issues that I've noticed so far.

iP4 32GB, no issues with it at the moment. :)
 
Week 27. No yellow screen and the reception issue, while not even a tiny factor in practical use, can be replicated if I grip the phone in the much derided hotspot.
 
Week 31
Size - 32gb
Color- Black
Yellowing - yellow screen but no spots
Proximity - No
Reception - When gripping tight enough, at tight grip and 1 bar - calls not affected at all, data slows to zero.
Pixels - No
Sleep button - No

This is my second exchange. Will att allow me to exchange for a third time? I bought mine at the apple store.
 
Week 29, 32GB. Can do the death grip if i try, but it doesn't affect my normal use.

Battery life is poor to average - cant get 2 days out of it. Seems to be a bit better after I restored and set up as a new phone. I had previously set it up using a backup of my 1st gen ipod touch.
 
bumping this thread. i'd like to hear more people chime in with build week info and whether they have signal and/or proximity issues.
 
Week 32 16GB

Can death grip the phone, but I don't hold it like that so no problem

No to the yellow screen
No dead pixles
 
Week 30 here on mine.

No yellow screen, no reception issues, just the damned proximity sensor is driving me nuts. :mad:
 
Week 32 / Aug
Production # within that week= 13763
Factory= 7S

No problems at all. Performing perfectly. Battery usage is way above what I expected. Getting 2 full days, and I use this phone a lot.
No screen issues or proximity issues either. I have the phone in a IvySkin "Reception" case but even without a case I have no reception issues.
 
It says week 33. My iphone 4 was week 25, but I exchanged at genius bar. They gave me a new one.
 
Week 34. No issues with reception and yellowing that I've noticed. However I do have some minor niggles with the proximity sensor during calls.

Amazing that it was only made last week as I'm in Australia and I bought it on the weekend, so that means it basically flew straight to me after it was made! I'm easily impressed ok? :cool:
