You must have the 2nd gen Touch – I have the 3rd gen iPod touch and it supports all the apps (iOS 5.1.1)

But if you don’t see the app available in the app store, then no older version exists (or WD doesn’t allow it), since Apple now allows older devices to download older versions of apps directly through the app store.
