Do you mean the Pets phone? The one that is metal and modern looking?

eta: I only use this phone, the base game one is stupid looking, but I also think the FT one is stupid too.

Here are the phones:
http://www.box.net/shared/lm1k9f2kn3I did a complete clone, they contain all the same internal filenames and GUIDs as the one from the game. That way if you use it in a lot and share it, it should show up for someone with Pets, but it also shouldn't package with the lot. And if you stick it in your bins folder it also won't have the *.
Please test it, I have no machine without Pets to test this on, but I set all flags for base game.
