Can my iPhone app register its own launch URL with a http schema, rather than a custom one?

Ive implemented this feature in a few apps without issue, but have yet to test whether it will handle custom web urls, like the YouTube and GoogleMaps apps do.

As Im not at a mac I thought Id pose the question as it will be useful for other people.

This question suggests its possible, but doesnt say how without using a 3rd party service: add custom URL Schema using http://

It may seem a stupid question but one of my devs needs to know and Im not there to help/test this at the moment

Yes! Here's a very nice tutorial on it: http://www.idev101.com/code/Objective-C/custom_url_schemes.html
