@Bones. There is really nothing to worry about when uninstalling/reinstalling. When you first go back into the game after reinstalling, all your buildings will be gray construction rubble and there may be other graphics errors, which can be really scary, but trust me, it all comes back within the next two or three times you log in. And it all still works (collects coins, reset stores, etc) even if its a pile of rubble.

I've uninstalled and reinstalled a few times and its fine. Since your tiny id is tied to your phone's ISP, the reinstalled game will automatically find your game and load it (the graphics come a little at a time, hence the rubble)
