Hello everyone. I recently got an Evo and I'm having a problem where I accidentally delete my widgets and since I'm not that tech savvy, It's a pain for me to try and find the exact way I had them. All I want to know is this; is there an app out there that simply locks your screens to where you can't move or delete your apps and widgets. Basically, what I'd like to do is have this lock in place so I can't accidentally delete or move something and when I want to make changes, i can enter like a password or flip a "switch" and it will unlock the home screen for changes for a duration of time. Does something like this exist? Thanks.
