Could I also ask, lots of people are asking about the FPS. I notice the app seems to have zero hiccups/ latency spikes throughout the UI, however the framerate does seem to be around 20/30 FPS in the map view on my iPhone 5. Is this intentional? It is a very consistent framerate it is just that it is noticeably lower than most every other part of the iOS experience.

I'm on an iPhone 4, and panning around is stuttering quite a lot. I'm looking at the downtown Seattle area in particular, if that matters. I'm wondering if the network speed has anything to do with it. I'm using 3G in a heavy urban area, so maybe it's hanging when fetching server data due to network congestion.

Panning around, rotate with 2 fingers, zoom in and out. Even the right menu animation is laggy.
