Yes, you can use the ROM. Its not customized in any way for AT&T. If you have an EVITA, it will work.
You will have to enter your carrier's APN info manually. And the ROM is not rooted (if you install with TWRP, it will ask you to root it automatically when you flash the ROM).
Also, if you get signal drop or random reboot issues, follow the instructions to updated the firmware as indicated in the first post of the stock ROM thread.
