Maps not working and soft restore not working

Ok heres the deal.

Downgraded 4.whatever to 3.1.3. And it worked, for the most part. went smoothly and the phone came alive much faster and smoother

Now, the soft restore (restarting the phone while holding the home and sleep buttons) does not work anymore. I know it was working in OS4.0 as this was a required step in the downgrade process. Now, it just doesnt work. Why???

And, maps will not locate my position and will not track anymore. I get the frozen blue circle of death and nothing else. And, it aint even close to where im at. If maps is on and the phone goes to sleep, when i hit the sleep button and slide to unlock it updates my general whereabouts on the map, but does not track.

WTF happened????
