I should go back and take a look at the exact wording of the Apple App Store rules but I never had problems submitting apps that use SSL.

There's one step of the submission process that asks about the use of cryptography and I've always picked the option that doesn't require submitting any additional paperwork - never had problems. I forgot the exact wording but I always worked under the assumption that SSL isn't what Apple is talking about when they ask about the use of cryptography.

If developers had to file paperwork with various governments just to use SSL in their app, then simply using one of the many third party APIs that require SSL (e.g. the Foursquare API) or even just embedding a web browser view that may end up loading an https URL would require the developer to go through the paperwork route to get their app approved. That wouldn't make sense.
