I just purchased a Curve from Verizon Wireless. I was playing around with it today and I created a folder to put some unused icons in (on the Home Screen). I moved a bunch of icons into this folder and when I click on this folder, there are no icons showing up. When I am in this folder, it BlackBerry Button (the one that brings up the menus) does respond. So I deleted this folder and no I cannot see any of my icons. Both the blackberry button and the back button are unresponsive. I cannot do anything except get into the web browser (which I set to one of the side buttons) and into the call log with the green phone button. Please let me know if there is a way to fix this. Thanks

I am having the exact same problem with my VZW curve. It appears it only occurs in the BB Dimension Icon theme.

Did you do a battery pull?

yes, several times

Did you apply the 8830 Software Update on VZW's site?

I did and still having the same issue..

Someone else started a discussion on the crackberry forums. Some people were extremely helpful in figuring out the problem. My situation is solved. Below is the link:

Good Luck

Wipe handheld and try again.
