Week 25
 
Week 28. 32 GB, black.

Got it today (iPhone 4 launched here today (The Netherlands)). Everything seems to work fine, although 3G drops when I'm in the living room (in the living room there's a bad reception anyway (1, sometimes 2 bars) so if I grip the antenna 3G will drop.

As far as I've noticed no yellow spots. No proximity sensor issues. Battery seems fine so far, but I've only used it for like 6 hours today (in those 6 hours I used it almost all the time. I started with 80%).

Reception - When touching the sweet spot only data upload is effected, download is fine. Voice calls are fine as well.
 
7/28/2010 - Apple retail Store
Week 30, found lines of dust under the glass.

7/30/2010 - same Apple retail Store
Week 31, replaced by a Mac Genius.

No case yet.
 
Week 30

Definite reception problems, although I deliberately death gripped the phone during a call, and even at 1 bar I didn't notice any degradation to the call.
 
Week 30.

Just got it today. Haven't had a chance to test the proximity sensor.
Reception: drop 1 or 2 bars max. I don't even hold it that way regularly, only to death grip. Use my left hand, but I hold the phone higher when I talk.
Will do some tests over the next few days.
 
Got it today. Week 31. Black 32GB, model MC319LL. Shipped with 4.0.1. Has reception issues. Slight proximity problems, and that's the extent of my troubles.
 
Mine is Week 29.

The camera and flash do not work anymore ( I got it yesterday)
The back glass 'clicks' when i put pressure on it (noise)

No reception issue
No yellow screen
Didn't notice anything with the proximity sensor, except that sometimes the screen stays black when it shouldnt
 
86022 - even though I bought it at the Apple Store on 7/15, the week where most others were seeing 27s (I went through "priority list" registration etc etc).

No proximity sensor problem.
No yellow tinting.

Nasty reception problem. If 4-5 bars, then I can still hold a call when grasping the phone normally. If under 4 bars, the call will drop if I touch the black strip. Since I'm usually in areas of 3 bars or less, I just "don't hold it that way" :)
 

+1

No issues. Although, in a side by side comparison to my 16gb that I'm selling on eBay (same factory, different week) the 16gb looks a little more yellow all around? Like my new 32gb has whiter whites? It's obvious putting them next to each other.

I like my new display better :)
 
Week 30, 16GB.

Drops one bar if I grip it in the forbidden place. (NB: My finger doesn't work; I need to death-grip it.) Not tested the proximity sensor yet, but no yellowing or other issues. Very happy!
