Officially, no. There is (or was) a hackish way to do it, back when iOS 4 was only available to developers and many developers found the pre-release versions too unreliable to use regularly. However, I'm not sure that this same method works for the actual public version of iOS 4.

It was pretty complicated and I wouldn't recommend it.
