Charging while on via wall socket still works.
I'm not debating whether this is a good thing or a bad thing. I just pointed it out in case Scott (or anyone else) is like me in this regard: I'm in the habit of leaving my phone on and plugging it into the USB cable off my work computer. Until the update, that charged my phone. Now, it doesn't. If you're in the same habit and don't know that the update caused the phone not to charge when connected in this manner, you might end your workday with a dead phone. Of course, if you need to leave it on and charge at the same time, you can always plug it into an outlet.
