IOS – iPad 2 Wifi + 3G With iOS 4.3.3 has no multitasking gestures

Both the latest Xcode 3 and the latest Xcode 4 allow you to mark an iPad with the latest 4.3.x as being "used for development". You can cancel if asked for your developer program credentials (which cost $99) and still have access to the gesture switch on the iPad.

Xcode 4 is only available presently as a $5 download from the Mac App store or with the $99 paid Mac Developer program as a restricted download. The free developer account (which still allows you to get Xcode 3) is fairly painless to set up as long as you can agree to all the conditions. You can see the various free and paid programs at http://developer.apple.com/programs/which-program/ - it used to be simpler but the free account is still fairly powerful but not on the cutting edge with pre-release

As with anything that is in software development, all things subject to change often and YMMV.

This does work with Xcode 3.2.6 and iPad if you make sure you connect the iPad to Xcode and check the box "use for development". You may have to enter an admin password and allow Xcode to scan the specific build (the exact wording of the dialog is hazy - but there is a step where Xcode gathers info about 4.3.3 on the device if your Xcode build shipped before 4.3.3 did.)

I don't use Xcode 4 or 3.2.5 so I can't be sure this works in general and you may need to ask on the developer forums or check the release notes to see what the minimum level of Xcode is needed to work with 4.3.3.
