Does the Blackberry browser support offline web apps?

Question

Does anyone know if the standard browser in Blackberry OS6 supports cache manifests and offline browsing? If so, would it be able to handle caching around 30 pages of data?

The reason is I need to make a call between developing a native app or a web app and this will be the deal breaker for the (quicker, easier) web app idea.

Thanks in advance for any help/advice.
