One of the best-received news coming out of the WWDC was Apple's decision to finally let users uninstall its iOS stock apps.

While some crucial apps, such as Messages and Phone, will still be undeletable, users will be able to remove more than 20 stock apps, saving space on their iDevices...

...or maybe not.

According to Apple's SVP of Software Engineering Craig Federighi, who explained how this will work on John Gruber's podcast, The Talk Show, users will be able to remove the apps, but not actually delete them.

The video of the podcast is not live yet, but according to MacRumors, once you "delete" a stock iOS app, only the user data and necessary hooks will be actually removed. The app will actually stay on the device; re-installing it won't download anything, and will instead simply make the app visible again.

That probably means that removing all those stock apps won't save nearly as much storage space as you'd expect — a bummer for users sporting 16GB variants of iPhones and iPads.

Other interesting tidbits from the conversation, which also included Apple SVP of Marketing Phil Schiller, include an explanation of some of the choices behind Siri's integration with Uber and messaging. According to Federighi, Siri best understands messaging and purchase requests, which is why Apple is starting with those kinds of apps. The company plans to expand Siri integration into other domains at a later time.
