I've had the gel cover since launch day and I've been noticing that the phone is getting awfully hot. Yesterday I set my phone up for some gps driving directions and the phone gave me overheating warnings after a bit. I tried the same thing after I took the cover off and everything was fine.
So be careful with at least the gel cover, it can cause overheating
