Nokia has recently announced the availability of Qt 4.5, a major update of the popular cross-platform application and UI framework and the Qt Creator, a new lightweight cross-platform Integrated Development Environment (IDE).
This release also marks an important milestone for the open source community. For the first time Qt will include the LGPL licensing option to go along with the Commercial License and GPL licensing options currently available.
In addition to the new product releases and licensing changes, Qt Software is also introducing a new flexible technical support package for LGPL and GPL license users. Developers using these licenses will now be able to purchase technical support from Qt Software.

Tired of the display backlight going out when you are looking at the screen - e.g. while thinking about the right word for an sms? Wouldn't it be nice if your phone knew when you needed the light and when not? SmartLight does just that: Once you have opened an application, the backlight stays on - until you close or hide the application, switching the light off automatically.
Once started, SmartLight runs as a background application. It can be accessed through the list of open applications (hold down the Menu key). With SmartLight running, the backlight stays on as long as the menu or an application window is in the foreground. The backlight goes out as normal (i.e. after the period selected in Phone Settings) once the user returns to the idle screen. The light also goes out as normal after receiving or making a call, and after the phone displaying system notifications (about new messages etc.).
