Store user preferences in a HTML5 WebWorks app

Question

I'm developing a HTML5 Webworks application for Blackberry OS 5+.

I have to store user name, password and locale. However, I don't know how.

I could use local store, but it is only available on Blackberry OS 6+.

Someone suggested me that I can write my own plugin, but I don't know how to do it.

How can I store user name, password and language on Blackberry OS 5+?

Use that link and maybe save to a file and read from a file? Its a shame you cant use local storage it would work great. What OS is it your using?

I've used it a few times and seems to work...
