I've been trying to think of ways to cool the eris without adding to the size of it. Lately, when I open the battery cover I smell what resembles burning plastic. Also, though I'm only clocked at 748, my phone occasionally stutters. This stuttering lasts up the 30 seconds. One idea that I've come up with is to cut a section of a pop can, and place it between the battery and the cover. For some reason HT thought it was a good idea to make both surfaces a non-smooth plastic. Been really busy lately, haven't got around to trying it yet. Another idea is to replace part of the battery cover with a plate of copper. Would look awesome, work awesome, and get weird looks next time you visit Verizon. Would also be a bit tough to make it look professional. The cooling fan is another option... Seriously though, any ideas? I don't know if my issues are heat related. Nonetheless, it's good to cool the thing to protect the phone and the battery. And I get annoyed at how hot it gets.
