Next N900 release (PR1.2) will include QT 4 in the default install. It has been delayed due to various problems observed in the leaked beta.
Also, N8 will be the first device supporting Qt out of the box. It is not shipping yet.
Nokia Qt SDK should allow unified Qt apps for Symbian and Meego:
It is not yet possible to deploy Qt apps through OVI store, so targeting third party apps to Nokia Qt is kind of pointless. If you need to develop to Nokia using a web framework, don’t rely on native QT Webkit, but target to Nokia WRT instead.
Nokia bought Qt in January 2008. It has taken over two years to ship the first Qt enabled mobile phone. Meanwhile, Apple has released App Store and risen to be the leading smartphone provider with its iPhone…. talk about slow development and the lack of leadership. So the hype around “QT will solve everything” is still just hype… they still don’t have nothing solid out there.
