I have rebuilt Symella with a new certificate, which should be valid for 10 years from now. The list of default GWebCaches has also been updated, and dynamic screen layout changes should work from now (rotating the screen won't mess up the UI).
I have tested the app on S60 5th edition (Nokia N97), and it seemed to work fine. However, please note that we do not have time to work on Symella any more. The only thing I can promise is little patches like this one in the future if I still see the demand (post your thoughts on the forum or send mails).
