Galaxy Tab 7" - can I install the original Android? any version would do I can't stand Samgsung's bloated customization of Android. It's slow and horrible.

Is there a way to get a custom rom for it? It doesn't have to be honeycomb or icecream sandwich. All I want is the original android system and basic google applications.

Particularly the Calendar and Contacts app are painful to look at. I would like to replace those with the originals, made by Google.

Is this possible? How?
There are quite a few Galaxy Tab roms on the XDA forums, here, most of them with instructions on how to do it.
