Retina (iPhone 4S): {F29776} Initial load. {F29781} Background of nav stays fixed after zoom. {F29772} Zoomed enough to switch to mobile, then back out again. {F29773} Initial load after rotation. {F29775} Rendering issues on vertical scroll. {F29779} Paste. Non-Retina (iPod Touch 1st Gen): {F29784} Initial load (notice avatar clipped to top corner). {F29786} Initial load after rotation. {F29788} Same rendering issues as retina, but worse. I think this is actually a browser bug not updating the CSS properly. {F29790} Paste.
