Yikes ddstrahm. Sorry about the trouble. If you're still having a problem making or receiving calls, please start out by restarting your iPhone http://bit.ly/tXe7I4. Many times these awesome smartphones can act like mini computers and just need a simple reboot to resolve quirky troubles.
If the trouble continues, I'll need to know a little more about what's going on. Are you getting any error message? What city & state are you in? You can follow & direct message me with more information.
