Something I missed from late last week. Om Malik regarding an interview with Mozilla CEO John Lilly at the Play conference:
…he hinted that the company was going to launch a brand new application for the iPhone, though he declined to reveal any details. “Mozilla will release an app to the iPhone App Store in the next few weeks,” Lilly said. “It’ll surprise people.”
Malik speculates that it could have something to do with Weave. Weave is Mozilla’s sync service which is currently a work in progress at Mozilla Labs. That seems likely to me, I definitely wouldn’t guess a browser, as some others have.
Apple has approved some browser-like applications for the App Store, but all of them use WebKit as their rendering engine. The likelihood that Mozilla would build a browser built on WebKit and not on their Fennec mobile rendering engine is essentially zero. I would also be stunned if Apple ever approved an application that used a third-party rendering engine.
