Nokia n9 browser
 

Hello, I'm writing this thread because I have some questions on the Nokia n9 browser.
Which version of Qt is it using? Because the performances are far better than a simpe qml webview compiled with Qt 4.7.4.
Is it using Qt 4.8 or Qt 5.0?
If it's using a higher qt version why it gets "only" 299 point on html5test.com? In fact if you test helium browser (Qt 4.7.4) you'll get over 320 points?
Thanks for helping.
