7720.68 is the latest version. It was called 7.5 and Mango, but the build always read what you have. If this is what you had prior to your reset, you should not notice any changes. I've never reset, but I recently set up my third Focus and this is as far as each has gone after a series of auto updates upon connecting to Zune. One easy check for Mango is that mango is a theme color option. Enjoy your great phone.
