I found iOS5 has my iPhone 4 running better than ever. It's not like the 3G going from iOS3 to iOS4.
I was going ask about that. How does it run on an iPhone 4? It's interesting that the 4S only have 512MB, just like the 4. I guess they squeezed it in.
When I got my 4 it was fast, but it seems the last couple of version made it sluggish at times, mainly when swiping though the screens or launching apps. The apps themselves run fine. I read somewhere it has to do with the way iOS takes a screenshot of everything so it can animate it during transitions.
