Lol, this seems to me like a money grab from Apple. Think about it. It's fairly difficult to do this on a PC, or being non-jailbroken, and for a small price of $5, you can buy Apple's software or register as a developer for Apple. Apple themselves probably leaked the Xcode trick just so they could make more money. Just sayin'.
A plausible idea, if you take the complexity of the other methods into account.
However, using XCode4 is by far the longest method of activating the multitouch gestures. Using ibackupbot takes 10min max, from reading the instructions, downloading the app, editing the plist and applying the tweak.
In contrast, buying&downloading XCode4takes longer, as it is, what 5GB? And then you also need to install it? XCode may be the simplest way of activating these features, but it is not a quick way.
