OK,so I have two questions. I upgraded to ios 8 when it came out on my ipod touch 5 and it's awesome! But is it normal(I mean for the public version) when I upgrade you know there was an option to share with app developers(so they could improve their apps) but isn't that only for the developer versions(betas) of ios? And in every app in the sharing I have the option to disable or enable some of the sharing options-for example on photos I can share on snapchat but I can disable that sharing option? I mean because I was using the betas before upgrading to public,is it possible that I have public version with additional developer features(which the non-beta users does not have)?I know it sounds crazy,but just asking.(Oh I also restored ios 8 beta to ios 7.1.2 before upgrading to public(a week before that.). So, the second question is you know some games are optimized for metal on ios 8 and will I see these optimizations on my ipod touch 5-is metal compatible with it-I mean will I see some difference or it i only for iphone 5s or higher? pls answer guys it will really help.
