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.

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.

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