Before you get too excited, the software so far appears to be light on new, user-facing features. Instead, one of the key improvements is new back-end technology that will let developers better use the company's homegrown maps inside their own applications.
To provide a frame of reference, it took Apple about four months to release iOS 5.1 after it released iOS 5.0.1. That update brought a reworked camera application on the iPad, and increased the size limit for over-the-air app downloads.
iOS 6.0.1, which went out as a free update today, fixed a handful of bugs -- including one that kept iPhone 5 users from updating over the air, as well as another that left horizontal lines on the software keyboard when typing.
Alongside the release, Apple also put out a new developer preview of XCode, version 4.6, for Mac and iOS software development.
