3G Metal Frame loose

Apple handles all iPhone repairs or exchanges under warranty.

Call AppleCare (800) 694-7466 to handle everything over the phone, or make an appointment at an Apple Store if there is one nearby.

Excellent. That is particularly an important replacement, since the main antenna is inside the metal bezel that is loose for you.

I just looked at my iPhone 3G 16 GB (Black) and noticed the same visible spacing in the upper left side of the display. This may explain why the other day my silent/ring switch popped off the metal cap. It appears to be a manufacturing defect. I'm taking it back to Wireless Wave (authorized Rogers dealer) where I purchased it to see if they can swap it for another iPhone 3G 16 GB since I'm still with in the 30 day return policy.

I had the same problem. I went to the local Apple store to exchange my phone, which the fella at the genius bar was willing to do, no questions asked. He DID state that he had exchanged 3 - 4 units for the same issue. And the replacements exhibited the same issue.

He gave me the option to go ahead and swap and I did. Sure enough, the replacement has the light defect, albeit not as bad as the one I turned in. Unfortunately, you can't just keep opening boxes until I could find one that I like. I guess I'll call Apple Care and have them make a note of this.

Instead of exchanging at the Apple Store, you can also call Apple Support and do it via the mail -- that guarantees you a different lot

I may give this a shot. I will say that the replacement that I have is from a different lot. I think it is the case because the iPhone I bought Tuesday was loaded with the 2.0 firmware. The replacement unit has 2.0.1.

Yup, that would be a different lot.
