I'm not sure this is the best place for this, but's not SDK development, and it's related to the web, so I figured this is probably the best place. Down to business...

Short version: I'm trying to make something of a character sheet for D&D (3.5 is my main focus). It would be accessed through any App Store application that allows you do download/upload files (such as Air Sharing) that can open HTML files. However, if I just use cookies, it can only keep a record of one character at a time. If I can use text files locally, then it can have any number of characters, theoretically. At the very least, a few. Is there a way to do this in JavaScript, on the iPhone OS?
