Just a quick post to spread the news.  In their recent webinar, Forum Nokia announced their intention to make Qt on S60 free for everyone.  However, from Qt 4.5, things are going even further than that (just announced on the Qt-interest mailing list).  Nokia are releasing Qt under the LGPL (v2.1).  For those that don't know, this is a weak copyleft open source license, which basically means you can use Qt on every platform for closed source commercial development, or open source development (LGPL v2.1 allows automatic conversion to the GPL v2 - they will still be releasing under GPL v3 as well).  The only real restriction is that any changes to the libraries must be released under the LGPL also (usual I am not a lawyer disclaimer here). The other major part of the announcement is that they will be opening their source repositories, hiring more Qt developers and making it easier for others to make contributions - apparently they don't need to get copyright assignment from contributors anymore.

P.S. The announcement said this is in addition to their commercial licenses (for those that can't live the the LGPL terms and/or still require support presumably).  I'm not quite sure how this fits with not needing copyright assignment, but we'll see soon enough.
