Here is a great resource for packaging and signing for distributing content on the OVI Store.
“The packaging format for Flash Lite content distribution depends on the target environment. For Symbian devices, the content must be packaged into a SIS file, and for Series 40 devices, an NFL file.
SIS files must be signed to install. Signing options for Flash Lite content are the same as for Symbian C++ applications.
Starting on June 23 with the public beta of Nokia signing Symbian apps for free, we are exploring a developer workflow to reduce the time for Ovi Publishers to two weeks and bring the cost involved to $0 (USD). At this time apps written with Flash Lite are supported. If you’re interested in participating in this public beta, please send an email to publishtoovi.support@nokia.com with your Ovi Publish username and you’ll receive more details.”
