Apple released an iOS 6 update this morning for the iPhone 5 and the iPad mini only. iOS 6.0.2 is a minor update that is supposed to fix a wifi issue that affects only those devices.
This is the only issue being addressed in this limited and minor update. Apple has not specified what wifi issue is being addressed, but users have complained about everything from poor recepetion to dropped connections in the past.
Users were complaining that they could not update over the air at first using the built-in software update tool, but that problem seems to have been fixed. I had no problem updating that way.
iPhone 5 and iPad mini users should be able to update to iOS 6.0.2 by going to General and then Software Update in the Settings app. Just press Install and agree to the terms and the update installs relatively quickly.
Some users who have installed the update have complained that their battery is draining more quickly than usual, but since the update was literally just released a very short time ago this morning, I'm left to wonder how much of that is the usual user paranoia over any new update.
Just to clarify: This update is ONLY for the iPhone 5 and iPad mini.
According to CNET, the update comes just a day after Apple gave developers a fourth beta of iOS 6.1. That software, which is expected by the end of the year, or shortly thereafter, brings new boarding pass behavior in Apple's Passbook software, tweaks to Safari, reworked music playback controls from the lock screen, ticket purchases through Fandango in Siri, and a back-end change in Apple's mapping software.
Apple's last update to iOS 6 was iOS 6.0.1 on November 1. That software fixed a handful of bugs, including one that kept iPhone 5 users from installing over-the-air software updates. It also fixed an issue with lines appearing on the software keyboard, and a bug that deleted meetings from calendars when accepting an invitation.
