I am not sure what you meant by you had ALT-Select and "change app command." You should use the Move command.
you know in the screen where there are tons of icon? (after you click in the blackberry icon/button from Today Screen)
In this screen where you see all of your applications, the first five icons are those that will also appear on your Today Screen.
Here is the screen with lots icons.
The first five icons appear on my Today Screen:
You can move your icons so that you can put any five icons/applications you want to appear in your Today Screen as the first five icons.
Just select an icon, press the BlackBerry button on the keypad, and a menu will come up, and it will give you the option of hide the icon/application, move it, show all icons (ones you hid)... once you choose "move," you can then move the icon with your trackball. press the trackball again to drop the icon at your desired location.
btw, do you use BB Messenger a lot? who do you talk to with PIN?
