I use my iPod for a lot of games and hardcore stuff like that.
iOS 6 really sucks on the 4th gen. It uses up pretty much all the ram leaving none for apps. Everything is super laggy.
I downgraded mine back to 5.1.1, and the performance is amazing.
----------
I'm really jealous, I wish I had stayed on iOS 4.
I'm still on iOS 5.1.1 and am thinking of upgrading to iOS 6.1.2 firmware. The main reason being that Safari crashes way too much. My touch came with 5.1 and I don't remember it crashing once. The problem is when Safari crashes, all my background apps have to start over.
I wish I had saved my iOS 5.1 shsh blobs but thought upgrading to iOS 5.1.1 would be fine (did it OTA).
I went to Apple Store few days ago and 4g touch had 6.1.2 software and Safari did not crash on sites it would always crash after zooming in:
-Google News Desktop version
-Apple iPhone 5 homepage
Could you try and see it these sites crash?
I also had my touch with me and it crashed at Apple Store to make sure it wasn't my wireless. 6.1.2 seemed fine besides music app taking 5+ seconds to load at first attempt plus these issues:
-New App Store/iTunes layout which I hate
-Removal of Youtube app, I liked this app since it was simple with no adds
-New music layout which I hate because everything is white
-Apple Maps, enough said about that
Also curious about this:
If interested in the free ram usage on my iPod touch 4g:
iOS 6.0: 80mb
iOS 5.1.1: 140mb
IOS 4.3.2: 137 mb
(Took along time to downgrade and restore back up to iOS 6)
I got the average ram after a respring and after clearing the memory 3 times but iOS 6 couldn't free the memory so average couldn't get a little boost like other iOS versions. I got the free ram numbers from sbsettings and sbsettings is not fully compatible with iOS 6 so that might of been a factor.
I defiantly noticed the lack of ram in apps. It's the first iOS version where stock apps crashed on me. Settings and the app store crashed 5 minutes in. (I always restore when I upgrade so that is not the problem)
I hope I gave you some insight what is going on with iOS 6.
I might update you guys later with better results when sbsettings is compatible with iOS 6.
