[android-developers] how to simulate an operating system upgrade...

i am having issues with my application when a user gets a system
update (for example from 2.1 to 2.2). i am wondering how I can
reproduce this experience on a phone (Nexus One). does this involve
rooting the phone and then applying a system update?

I need the update to look as though it came from the system. In other
words, I can't take a full ROM image, because then I think I would
lose my application being installed between upgrades.......

ideas?

tia.
