Mobile Network not connected... I think

First let me say that I dropped my phone in the toilet :( so the trackball will not let me click on anything. My phone lets me make calls/send texts when I am around WiFi... but not otherwise. I can't check the box under "manage connections" for the mobile network to connect. And under Options > Mobile network, this is what it is saying " Data Services: On, Connection Preference: Mobile Network Preferred, Mobile newtork: *none*, Network Selection Mode: Automatic."

Not really sure where to go from here...

What carrier do you use? If you use VZW, try doing a *228 and update the roaming on your phone.
