Motorola ROKR Java Application - PLEASE HELP ME

Hey guys.

I just got the Motorola ROKR and i am loving it. Everything works exactly the way i expected it to work except that i cannot transfer java applications from one phone to another. I have an application on my phone called "Safe" made by "KeyCriteria". It lets me store all of my passwords and sensitive information securely and only accessible by a password. I have put in a password assuming i can change it to another one later, but it turns out that I cannot change the password. In the help files it says that once the password is set it cannot be changed. My brother has the exact same phone and has not entered a password so i would like to copy the application from his phone to my phone using bluetooth but it will not give me an option to do it. How do i copy the file from one phone to another, or if somebody knows how to change the password in Safe I would greatly appreciate it. Or how do I copy it to my Powerbook via bluetooth or cable from my phone to my brothers phone.

When i go to the App it only gives me the folowing options:

*Sort By Size
*Details
*Delete
*Permissions
*Switch storage device

The details on the application are:
Name: Safe
Vendor: KeyCriteria
Version: 1.2.7
Apps: 1
Data Space: 97 K

I have bluetooth on my PowerBook so it will not be a problem to transer to the computer.

Thank you in advance and PLEASE HELP ME!!!
