Detailed feature list for each firmware?

[XR219]

Hi Guys,
Is there a detailed feature list that outines which features are in which firmware. I have successfully debranded my Sony Ericsson Elm, however quite a few of the features, i.e facebook etc, which should be on the generic phone are no longer there. When you use the client there is a list of customised firmwares, but is it possible to find out what is in each one?

thanks for your help.

Sony Ericsson issues an overview of most releases on their site - otherwise, for provider-branded firmware, overviews would be released by the provider in question. Generally flashing from the latest available revision is the best bet though you may sometimes prefer some provider additions (such as Facebook in your case).
