Lately my curve has been acting really weird for lack of a better term. It will go hours without getting any email, and then all of a sudden get a flood of the last hours mail.

It will show calls just by the number instead of by the name in my contacts.
When I lock the keyboard sometimes it will not come back up, the screen will stay black for a long time and I have to press the button several times to get it back on.

When I use the camera at times it will take a picture and if I don't close the camera the screen will go black and the phone will reset itself (with the Blackberry logo and status bar, like I took the battery out). What's going on? I turn the phone off every night, and I've tried taking out the battery and resetting it. Suggestions welcome, please??

Did it get wet?

Nope, never wet, and I checked the little white square inside just to make sure. This is actually my 2nd 8900, the first one I returned for warranty issues due to lack of reception and a weird echo during calls.
