Is it possible to detect when your BlackBerry has been reset or you've removed the battery?
Weird question, I know but it would be awesome if it's possible.

Actually Simon's answer was correct if perhaps a little too brief for you.
Here is a little more.
The usual way would be to have your application autostart. Most people do this via an Alternate Entry. So they have a part of their application that autostarts and sets everything up, and another part that runs when the icon is pressed. How to do this is described here:
Be aware that an application is also autostarted on initial install. To detect the difference, you need to check, in your autostart application, that the device is 'inStartUp - see
Hopefully this is enough.

Basically, I have a persistant store for certain objects/variables that I use for "run once" case. In this case, ApplicationMenuItems, but the issue is that if you've rebooted your phone then the menu items need to be reregistered. At the point, my variable/flag is still set to show that the menu items have been registered and thus, will not register them again unless you remove and re-install the app ... o_O

Yes, but I use that to mean 'reset'. In other words, at start-up time, if the RuntimeStore object is not present, the application knows the device has been restarted or the application is freshly installed.

yes you can detect battery pull or device restart , just make your application autostart and implement SystemListener in your application , you will get call on powerUp().
