This weekend GigaOm brought word that Mozilla was working on an iPhone app. Of course, thoughts turn immediately towards their most famous product -- Firefox. However, Apple doesn't allow 3rd party code interpreters and that means no Gecko HTML renderer and no TraceMonkey Javascript engine. And again, I don't think there's any need for Mozilla to make a WebView wrapper...

So what else is there? Browser link sync? The iPhone will sync Safari links, or Internet explorer on Windows, but syncing links for Firefox users is thus far unsupported, and no doubt many would love to have that functionality:

Later, I sat around gabbing with Lilly and Jay Sullivan, Mozilla’s VP of Mobile, talking about Weave and the Awesome Bar, which is a way to get access to all your browsing history and bookmarks by just typing them in the URL bar on your browser. And while we were talking about Weave, I asked them if it was going to be part of this new, mysterious iPhone app. Lilly and Sullivan smiled and remained silent. Interestingly, they didn’t correct me.

Malik notes that Weave might be too competitive with MobileMe for Apple's tastes, but that of course will depend on the exact implementation offered on the iPhone, and how flexible Apple is feeling (more so than ever, it seems of late). And if ever a Weave there was, bringing it to the iPhone certainly makes sense.
