Opera just released a new, minor revision for BB (it's reporting v5.0.19692).
http://m.opera.com
Reported improvements:
A bunch of language support.
RSS feed links should now appear at the top of pages again.
RTL (Right To Left) languages should now display properly on phones with supported fonts.
Problems with daylight savings time have been fixed.
Some problems with keypad text input have been fixed.
Alas, it doesn't fix the keyboard ghost problem - I still have to rotate to get the space back.
