it might help.

From canvas properties you get the Screen Size

You can also may a request to WURFL database and server hit that can get you the device details based on user agent.

Hi InvisibleCat

I did a nice trick to get all screen dimensions for my application (it is not a canvas application).
As I have a full splash screen (canvas based), I retrieved all screen dimensions when my splash was been displayed.
I saved these values and I used them later in my app.
