Find My iPhone app - earlier version

[oxoxtro600]

I have an original i Pad running OS 5.1.1 and want to add "Find my iPhone" app. iTunes has only the latest version which requires OS 7.0.3. Where can I find an earlier version of this app?
Thanks

Do you have the older version synced to iTunes? Other than that, I don't know where you can get it.
