Help with Erica's doShell.app

Im trying to use Erica's doShell.app to create a springboard icon that I can tap to run her findme application. Problem is every time i upload it to the phone my spring board freezes until i delete it? Anyone out there know what im doing wrong and how i might be able to fix it?

Thanks for any help.

Ok, i got past that problem now when I tap the program on the summerboard all i get is a white screen. I have the doit.sh set to run the findme program but it doesnt appear to do so. Any help?
