Hello,
To develop flashlite content, you need to select the flashlite project option
from within Flash MX Professional 2004. There is a flashlite1.1 CDK that has a
few examples/documentation. This is available through the macromedia downloads
page.
As for playing flashlite content on your mobile, you should look at this
