I will occasionally shut down and pull the battery out for 30 seconds. That "reset" does wonders. Next I would look at applications and the settings - Maybe you have alot of activity fighting for processor, memory, and/or bandwidth. A call to VZW tech support can be helpful as well. Good luck.
i've only had my curve for 2 days
the first day it rebooted once while viewing pictures and again while sitting on the night stand
next day it was fine all day no issues
then last night it rebooted again while sitting on my night stand
nothing was running and the only apps i have installed are pandora, google maps, and vz navigator
Hey on those apps you have installed, I would check to see that they are not setup to push for updates.....like how Google news website automatically pushes to update its own website on your PC. Your culprit may be the Google maps or the navigator. I would check your settings to make sure they are not setup to automatically find you location. Your app could possibly be pushing in the background even if you don't physically have them running.
P.S. Battery pull in the mornings after you take the device off your charger..this is true for most PDA's
