I checked S60 FAQ today, and figured out an interesting chapter.

Is Flash Lite from Adobe going to be available on all S60 devices from S60 3rd Edition, Feature Pack 1 onward?

No. Flash Lite from Adobe is an optional component of the S60 platform from S60 3rd Edition, Feature Pack 1 onward, and it may not be implemented on all devices. However, end users can install Flash Lite on S60 3rd Edition devices that ship without it.

A Flash Lite Framework API, which allows developers to interact with the Flash Lite 2.0 player and later versions, is present as part of the S60 platform. However, it works only on a device that has the optional Flash Lite 2.0 player or later, either as an original component or installed by the user.

From that, we learn that not all S60 3rd Edition FP1 devices will have Flash Lite for sure. It’s mentioned that end users will be able to install on devices that ship without it. Does that refer to free Flash Lite 2.1 player or is there other ways? An open issue for me. Also, anyone understanding the second paragraph, come forward :)
