Im involved in a ongoing thread in the apple community forum about full screen incoming photos!! It's not in the beta version just yet but hopefully!!!!!! Lots of people how downloaded it already made comments about it not being back just yet I'll comment again after the first beta update.
I'd appreciate it. My eyes are finding my iphone less and less friendly. Interesting that the ads show full sized photos but no song in the beta. Looks like they know no one would find that little circular photo a selling point but of course, that doesn't mean they are going to change it.
