Whats the best way to uninstall an app on 7.0 Nought?
AFAIK, using "drag to uninstall" and uninstalling from app manager area is one and the same thing - only the the former is a shortcut to the latter.

Here is why:

Consider an application dragged to be uninstalled:



It still accesses the built in uninstaller from App manager



When directly using the application manager to unistall:



The difference, is when you "drag to remove" or when using a completely different uninstaller from third-party developers.



Hope this helps
