Agh, look what I've done ;) Sorry I asked. I did a search earlier and only found a mention of the vibration mechanism on the 4/4s causing a sound, but figured that was not the case here. Anyways thanks for clearing it up. For the record, my 5 didn't have this issue, and I wanted to make sure my $900+ didn't come up with a problem. I'll go hide in a hole now..
 
Ah yes, the annual camera-lens rattle thread. Good to see that it's on time this year.

Not camera lens, please read original post, it was my power button. Anyways, sorry for posting.
 
My 4S has done this's for two years. My 5S that I got yesterday does this now.

Whatever it is, it's a non-issue. No need for folks is this thread to get their jimmies rustled.

Enjoy your phone!
 
I have my 5 and it never did this and still doesn't, opened my 5S and I can notice the rattle and feel the power button jiggles side to side when I touch it. It makes a noticeable rattling noise. Gonna see if they can fix it or replace my phone.
