Dropped calls
However, it has happened at home, as well.
Is this what was happening with the at&t iphone? I did a little quick internet searching but seemed to only find articles that talked about webpages being loaded extremely slowly when one held the Verizon iphone with the "death grip."
I was a Verizon customer the past few years and did not have this problem with my other cell phones.
