Heat?? How much heat could there be in new box inside an air conditioned store?
Example from a recent post:
"2ND POST: 8/5/08. 7PM.
Here's an update folks... the new iPhone 3G I was given as a replacement on Sunday, August 3rd to my original phone that had developed cracks in the casing has now itself started to crack... yes, that's right, I found a crack near the volume rocker switch today. I took it back to the original genius at the SF store and he pulled out another new one, it already had cracks right out of the box, he pulled out a 2nd, and a 3rd... both had cracks in different places... it wasn't until he pulled a 4th out that we found one with NO cracks. Now I'm home, its all set up and we'll see after the next couple days if this one develops cracks. This is a major major issue that I don't think too many people are aware about, simply because most of those still standing in lines to get the 3G iPhone don't watch macrumors.com or the discussions on here. Spread the word folks or nothing will be done about this."
