No, there is Skype for Android (which is available for any carrier), it's just "wifi only" in the U.S., but most people should be able to get their hands on the non-U.S. version if they know how to use google.
The sheer suckiness of US networks never ceases to amaze. For a supposed 'technology' country it's amazing how backward they are, and just how much they have customers by the balls. And the customers don't seem to mind.
