GigaOM interviewed Mozilla CEO Jon Lily at the Play conference, an event at the Haas School of Business at the University of Berkeley. There, Lily hinted that Mozilla would be submitting an app to the App Store.
“Mozilla will release an app to the iPhone app store in the next few weeks,” Lily said. “It’ll surprise people.”
While Mozilla's business is mostly browsers, they do other related stuff and they aren't likely to try to get a Safari competitor by Apple's App Store reviewers. Om thinks it might revolve around their bookmark synching service, Weave.
