Cant install Qt Application on Nokia device

From QtCreator I chose Mobile Gui Application and did not change a line of code. I built it using simulator and it works fine. When I try to dep开发者_开发百科loy it on to my device I get a warning 'Application not compatible with Phone. Continue anyway.?' Obviously the app is not working on my device.

I have installed Nokia Qt SDK 1.1 and have installed Qt 4.7.3 ( including QtMobility and QtWebKit ) which comes with the SDK on to my device.

What am I doing wrong?

Thanks

Maybe this thread on forum nokia solves your issue. Which device do you have?
