And I'm not talking about the Apple Maps fiasco. iOS 6 has failed on my iPhone 4 in the form of twice, not being able to answer a call.
The screen was unresponsive, so I couldn't click answer or unlock the phone. In one call, my repeated tapping and swiping some how triggered the phone to start playing a Wilco song. The iPhone was still unresponsive so the song just kept playing until it finally let me unlock the screen and turn it off.
<sarcasm> Nice. </sarcasm>
On a call today and after I ended the call, the phone started playing the podcast I'd been listening to during my commute.
<sarcasm class="dripping"> Nice. </sarcasm>
Speaking of Podcasts - first time I jumped in the car and went to listen to one was when I discovered that they were no longer there! Had to download the new Podcasts app - and re-subscribe to all of my podcasts.
<sarcasm class="biting"> Nice. </sarcasm>
