There was an update to Jetpack Joyride released today, which makes me consider replaying the game (I lost all my progress when I updated to iOS5).
However, I am a bit confused by how I actually get the new missions.
The update text includes the following:
Please note that the new mission system is only playable AFTER prestiging at least once. If you have already prestiged and get the update, any mission you get after your current missions will automatically transition over to the new ones, yay!
What do they mean by "prestiging at least once"?
