Default Are all rear covers (battery doors) the same. Dog chewed mine!!

Since there are multiple carrier versions of the G2, does each one have different antennas in the rear door?

See here is the problem, my friends dog used my G2 as a chew toy (he is a puppy and I left the phone out). Luckily the phone works, no scratches on the screen and the parts inside the phone were all undamaged. The dog did chew the hell out of the battery door, so much to snap it in two!!!

Now I've seen some sold online, will any version work on this phone? I don't care about the door not having the Vz logo on it.

Ive seen doors for the Optimus G2, but that is a different phone, correct?
