Apple also gives a couple more apps the iOS 7 design treatment.    



From ArsTechnica:

Apple has just released iOS version 7.0.4, an update for all devices running iOS 7. Unlike iOS 7.0.3, which fixed a fairly extensive list of small bugs three weeks ago, this patch addresses only one specific bug that would apparently cause "FaceTime calls to fail for some users." Other "bug fixes and improvements" are promised but not described in detail. Apple's support site doesn't actually feature any details on iOS 7.0.4 just yet, but we'll update this post if we discover any other fixes of note.

In other, tangentially related news, Apple today updated its iBooks app for iPhones and iPads with a new iOS 7-style design, replacing the wooden bookshelf texture from the old version. The iTunes U app for educational institutions has been given a similar makeover. Most of Apple's other apps (including the iLife and iWork suites) have been given the iOS 7 treatment by this point, and with the new iBooks and iTunes U versions, the transformation is mostly complete.
