Help No edge or 3g???


I got my vibrant a couple weeks ago and its been awesome. Last night, I was downloading apps... after messing with Extended Controls, I noticed that my "edge" icon wasn't showing up. I tried switching my phone to 3g, and that icon didn't work either. I can make phone calls and stuff, but I can only use the internet if I have my wifi on now. :(

I uninstalled extended controls, but that didn't help either.

Does anyone know what I could do????
