Although it was initially scheduled to be released two days ago, the Opera Mobile 9.5 Beta launched today. You can download it and test it out as long as you have a Windows Mobile 5 or 6 powered touchscreen-only smartphones.
The two days delay was caused by the discovery of some bugs which needed to be taken care of prior to the release.

It’s still a beta version so various problems might still occur. Test it out and report them to the Opera guys. Opera Mobile 9.5 promises to be a very dependable mobile browser. And let’s not forget that Safari mobile is also out there and that Mozilla is working on their Fennec mobile solution.
