I live in South Florida, it's hot 75% of the year here and the humidity is just as bad. I just got the cheap $1.99 vent mount for my EVO and love it but I noticed with direct vent exposure the screen tends to fog up and the battery temps drop as expected. Now is there any major issue with this? Will I see any problems down the road with the screen or internals because of the condonsation? I've since closed off the vent that holds the phone and it seems to be working but I kinda liked seeing low low battery temps and was just wondering...
