Dev Team,

The symbology and tile imagery in our iOS application appear blurred on the iPhone 4???s Retina Display and we're not sure why. We've created the necessary images in both resolutions to support older versions of the iPhone, but we're not sure what we've done wrong. There don't appear to be any articles or resources on the current SDK's support for the Retina Display. I???ve attached a screen shot for reference. Notice how all the other graphics are nice and crisp and how it contrasts with the fuzziness of the tile imagery and symbology. A few questions:

- What might be causing the fuzziness and how can it be resolved? Is it something with the map? Is it something with the AGSPictureMarkerSymbol?
- What if we wanted to use Bing maps tile imagery, would those tiles be fuzzy as well when accessed through the ESRI iOS map View?

Thanks for your time,
- Aaron
