I updated my ipod touch yesterday, the update took awhile and I wasn't hesitant at all since I don't use Maps very often on it. When I first started it, I was able to start and run apps more quickly, and it seemed less laggy in general. After heavy usage today, it seems to have started being laggy again.
In terms of the updates, Maps isn't that bad in my city (Toronto), and Apple actually uses Yelp when you look up certain stores or locations, which I found interesting. I personally don't really use streetview, so I haven't seen any weird things yet, lol.
Major improvements on app store UI, which I really like. They now have some nice horizontal scrolling implemented for search results when you search for an app.
I find it stupid that the passbook app just leads to a list of Passbook supported apps in the App Store. Alhough right now I'm facing the same Passbook problems as other people in the Passbook thread
Facebook integration is pretty awesome, I love that I can now sync my FB friends to my contacts, and Facebook events to Calendar! Being able to post from the notification center is also pretty cool (
even more handy on Mountain Lion).
What else.. lots of cosmetic changes on the default apps. Oh, they add a 'new' banner to every app you've installed but never opened before (pretty useful little feature).
No camera changes on iPod other than cosmetic ones, no Panorama (lol boohoo)
Game Centre improvements, including FB integ. so now I can add my FB friends who have Game Centre. Challenges. Etc.
Anyways, there's not much to say since all of the iOS6 updates are the same as iPhone5, except a few missing since we're only on the A4 chip and have a crappier camera.
To person who suggests not jailbreaking: totally agree. Lol. I found it really laggy after iOS5, unfortunately.. Don't think it'll get any better once there's a jailbreak for iOS6.
