You will most probably be glad to hear fresh news from the Qt for S60 port team. They have a new release* out, it is called Tower and it is based on Qt 4.5.2.

There are many new things and many improvements on the existing features, you can see them all listed in the Detailed list of changes for "Tower". To name just a few:

• "Experimental" support for QtWebkit (must be enabled at configuration time)
• Phonon support but without the actual playback capabilities.
• QtSql with sqlite3 backend
• Improved exceptions safety for Qt Core library (this comes with a patch for the Nokia C/C++ compiler and some really promissing documentation, judging by the title )
• Input methods

All these and a lot more in an 126 MB binary installer which is smart enough to detect all compatible SDKs in your system and install "Tower" support in all of them. (From what I see the installer needs a bit of optimization or I need a new computer )

You can find all the binaries, documentation and support information on the Qt for S60 "Tower" pre-release site. Coming soon support for Samsung's S60 devices, an updated version of the Qt for S60 Developer Library here on Forum Nokia and a new release of the Mobility Extensions APIs.

*Please note that this is still a technology preview release and it is not yet ready for production grade application development.
