25th week for me. I have reception issues and the yellow band across the lower part of the screen. Since it was just manufactured last week, perhaps the glue theory is true.

That may be! But again I hear that the yellow thing will go away.

So far, the oldest is week 18. The newest is week 25.

 

[AJerman]

23rd week for me. Black, 16 GB.

No yellowing, yes reception goes down if held on the left. (I really don't think we'll see reception issues be based on the date)

Now link this up with if you have yellowing issues. Assuming they are caused by glues that aren't completely cured, you would have the latest manufacturing dates.

Edit: Damn, you guys keep beating me to the punch today. Someone already mentioned yellowing based on date.
