How to Update to Windows Phone 7 Mango Beta for All
only catch is that you will have to create a backup your current official NoDo config IN A SAFE PLACE!!! and then when the official Mango is released in the fall, you will have to restore your beta Mango Arrive back to the NoDo backup file. this method of updating is for developers, but your phone doesnt know that you aren't a developer
