So yesterday I was fine, google maps, fandango, facebook. It was all fine. Now all day I have a crap single everywhere I go, and places (like my room) where I was getting a fine signal yesterday and now it sucks and I cannot get onto any of my apps because of it.

And yes airplane mode is off, I am not roaming and I am not getting that little EV in the top right corner to let me know I am in good signal area.

Any thoughts?
