Team ChevronWP7 have released a program to update all WP7 devices to the
latest version of the operating system. Due to that fact, there is no need to wait while it will be officially released by Microsoft.
It includes the pre-NoDo update, and the NoDo 1 and
NoDo 2 updates that have been rolling out for certain WP7 devices in
different parts of the world.
But, since the update remains unofficial, you will bear full responsibility if anything goes wrong.
