OK, I know the horrible experience of flashing a ROM and seeing "emergency calls" or "no service" so I'm making this thread to show how I got my own phone back. I actually done this without an efs backup so if someone has a different way, that works, feel free to post it. First off, I want to thank Funkylogik for trouble shooting with me, Heat 57 for giving me advice and tips, and everyone else who isn't afraid to jump in and help people on this forum!
1) download the "stock" firmware.
2) factory rest your phone.
3) open Odin and allow the program to detect your phone.
4) click the PDA button and place the stock firmware that you just installed in that box and press start.
5) wait
6) wait
7) when Odin is finished, restart your phone and voila it now has signal again!
The phone will now need to be rooted again.
