Help I think I messed up...haha

Good morning. So last night I went through the process of using gingerbreak to root my phone. Everything worked really well. I down loaded titanium and rom manager. I backed up on rom manager and with titanium i deleted a file, i think it was called voicedialer, basically it allows me to dial out and get service. Now my phone no longer has service, and I can't place calls. haha I assume what I did is not fixable. Is there anything I can do to recover? I tried loading the rom manage back up and the back up was not saved properly. Is there a way to down load that specific file to patch my system. thanks for your input in advance, off to work.
