Still no Windows Phone 7.8 update for you when it should have been here yesterday? Windows Phone hacker got you a solution to easily install Windows Phone 7.8 update today. You just need to press install and chooce the right language pack and you are ready to go.
Basically, the tool acts as a wrapper for the UpdateWP file, and contains all the updates and their language packs. Using this tool has the same risk as using the manual cab method, so keep in mind that I’m not responsible for the chance something goes wrong, despite that being very low. It’s also a tad experimental, but it seemed to work for a great deal of people while I was sleeping, so have at it
I also tested this on my Lumia 800 with no problems.
