I post the supported phones in the SDK v3.0 here for reference. This is also listed in the documentation but if you want to know if it's the right one for you before downloading it, you will be quicker.

That's Nokia's official list at the release time of the SDK.
If your model is not on the list and it is newer than the release time of the SDK it might also work if it's compatible. So you could give it a try. If the model is older than the release time it could also be that it will never be supported by this SDK at all, because it is too incompatible.
Maybe we can compile an updated list of supported models ourselves. If you - or anyone else reading this here - can find out more models compatible to the SDK that are not on this list, post that here.
