In case you are not aware of the on-going development of eSWT for Symbian
platform in Eclipse eRCP project (http://www.eclipse.org/ercp/).
You are more than welcome to try the implementation out in your Symbian
S80 phones and report bugs/comments to eRCP newsgroup.
You can get the source code from the eRCP CVS. To compile and build the
code, you need the Series 80 SDK from Nokia Forum
(http://www.forum.nokia.com/).
Note that you must get Series 80 Developer Platform SDK's for Symbian OS,
for Java (Personal Profile), not MIDP.
