Lots of speculation surfaced last week at AllThingsD's D10 Conference after comments made by Tim Cook. "The juices are flowing, and we have some ," said the soft-spoken Apple CEO.

Last month, AllThingsD and the Wall Street Journal reported that Apple will be delivering an in-house iOS mapping solution to possibly replace the native Google maps app. Of course, this isn't surprising given that Apple has acquired three mapping companies in the past three years.

One of those companies, C3 Technologies, has photorealistic 3-D mapping. If this makes its way into iPhones and iPads, expect to see 3-D cities.

Does Cook have something cooking with Facebook? If you want to share something on an iPhone or iPad, you can tap the share button (i.e. rectangle with the arrow coming out of it) that's built-in to iOS. You can email, Tweet and even print but not share on Facebook.

While Apple will need to work closer with Facebook down the road, probably nothing will be announced next week. Mossberg pressed Cook about this issue, and Cook responded somewhat dismissively and without a whole lot of enthusiasm: "Just stay tuned on this one."
