Can't imagine a reason why it wouldn't be allowed on the iPod Touch. They are the same OS, with the touch not getting the phone app a few other back end things.
Thanks, and I agree that it does run the same OS. As you said, there are some features that are currently iPhone only. The fact that the image shows that it is using a 3G connection is indication that it works over 3g, but may not (for whatever reason) work over WIFI which would obviously exclude the iPod .
