I've heard a friend download the beta.
I'd like to know if camera has the timer-option because that was something useful.
Also how about the battery? I've seen new effects would that really affect battery performance. I don't think so but would be interesting to know before moving.
Anyway we have time. It will be released on "Fall - USA". I don't know when is that but .. ok.
I've seen new good functions just like swipe to close open apps. Yes, yet you have to press the home button twice to access it but you don't need to hold anymore the icons to close it. I think is much much more useful now.
The only bad I see (I know it will sound silly) but the new icons are .. pretty ugly. They are really nice on iOS6, dunno why they put less details on the newer ones. They are trying to look like windows 8, all very simple. It looks good on W8 but I don't think is pretty cool for apple. And well I've seen a lot of white screens. I mean white will be the dominant color, perhaps not the best choice since it will be very brighter and eyes-killer.
