Data Problem

[uscjunkie]

Everything was working fine as far as my data connection goes. Then I started playing around with clocks and themes and noticed my data wasn't working. So I looked in the communications setting and saw that my data connection says off. I click on it to try and turn it on but it lights up gold but then never does anything. I had screwed up my clock anyway so i decided to just hard reset thinking that would fix any problems but I still can't get my data connection back. Anyone know what could be wrong with my data connection?
