The Nokia Qt SDK leverages the power of the Qt framework and tools, combining them with tools designed specifically to streamline the creation of applications for Symbian and the Maemo platform. 
The Nokia Qt SDK allows you to explore how building applications to take advantage of the enormous customer base offered by Nokia will become even easier.
The Nokia Qt SDK delivers tools that will accelerate your cross-platform apps development. Among these tools, the Qt Simulator enables you to simulate many aspects of the behaviour of your Qt based app on any computer running the Nokia Qt SDK.

Simple to install:
· One simple to install package is all you need to get started. No complicated setup, just connect your devices and your environment is complete.
Develop rapidly:
· Intuitive yet powerful tools, such as Qt Designer and on-device debugging, will power you through your development. Think it, do it, it’s that easy.
Lightweight simulator:
· Find out how you application will work on any Qt enabled device quickly and easily. No need for complex device emulators just let the Nokia Qt SDK do the work.
Complete tool chain:
· Find everything you need to go from application concept to fully tested, ready to deploy application in one place.
The power of the Qt APIs:
· Forget long complicated programs, the power of the Qt APIs lets you do more with less. Need to know a location or send a message? The new Qt APIs for mobile development are built right in.
One code line, many devices:
· Want more customers from less coding effort? With Nokia Qt SDK and the power of Qt you can quickly create applications for both Symbian and Maemo devices.
Remote compiler:
· Compile your Qt app to any platform from any computer. With full reporting and click-into-code compiler feedback, the Remote Compiler enables developers using Linux or Apple Mac
Smart Installer :
· Symbian apps no longer need to bundle the full Qt framework within their SIS files. Smart Installer downloads Qt and Open C/C++ components as the app is installed. With signing done by the Ovi Store, distribution of Qt apps for Symbian is now even easier.
· Qt Simulator
Simulate target devices:
· The Nokia Qt SDK offers simulations for all the device platforms you can target: Maemo Fremantle, Symbian touch, and Symbian non-touch
Test with platform data:
· Making use of the new Qt APIs for mobile development? Use the simulator’s features to feed location, messages, contacts, and other data to your applications for testing.
Device states on the fly:
· Want to know how your app reacts to low battery or loss of network? Change critical device statuses on-the-fly, from the simulator toolbar.
Innovative zoom feature:
· Trouble visualising how your application will look on a screen the size of a real device? The Qt simulator zoom the device view down to let you see.
Create a dynamic data:
· The simulator supports scripting of platform data using the JavaScript language. So whether it’s device motion or an intermittent network connection, they can be simulated easily.
Start simulation from Qt Creator:
· There are no complex setup requirements: choose the simulator as one of your build type and run or debug your application straight from the IDE.

Limitations:
· Please note that apps created with the Nokia Qt SDK for the Nokia N900 mobile computer require the device to have firmware version 10.2010.19-1 or later.
