Are OpenType font features supported in any iOS web browsers through CSS?

[!!!nuttCeriNerge]

The current version of desktop Chrome supports OpenType features through CSS.1) My testing shows that neither Safari nor Chrome on iOS 5 support OpenType features. Is that right? (I know I hav the right \[code\]-webkit-font-feature-settings\[/code\] CSS tags, because the OpenType features work fine in desktop Chrome.)2) Is the situation different on iOS 6?
