When I reset iWedding what actually happens?
Resetting iWedding means that all the groups added to Contact List App are removed. It will not remove other groups that do not belong to this application. This does not delete the contacts from the iPhone/iPod Touch, just removes them from the iWedding groups. Reset also means that all Business and Guest Application Data is deleted. The Application then Exits to your devices Home Screen (to the user the screen will simply go black and go to Home Screen). If you happen to open iWedding again, the groups will be recreated and a new, fresh and clean Database will be setup.
