i found out how you can enable multi-touch gestures on your ipad.
you have to buy and download XCode from the Mac App Store ($4.99), and it's about 4.3 GB or somethin like that, then you follow the directions here. it's really, really easy. i found this yesterday by chance on twitter, because i'm not a dedicated gizmodo reader or anything. i don't know how you could do it without having a mac though and the xcode.

1. Purchase Xcode 4 and install it.
2. Launch Xcode and connect your iPad to your computer. It will appear in the Xcode's devices list.
3. Click on the "Use for development" button.
4. When it asks you to enter your iOS developer credentials in the dialog box, click cancel. It will give you an error. Disregard it.
5. Once the developer mode activation is completed, go to your iPad general preferences menu and turn on the new multi-gestures.
it kinda sucks that it takes up so much space for xcode but whatever, i think it's pretty cool to have on the ipad.
