While most of us are still waiting for software update for Nokia E71, you can update Opera Mini browser to new beta version marked as 4.2. New features mentioned in change log are: supporting skins, new proxy server for customers in Americas and Asia-Pacific region, mobile YouTube (m.youtube.com) support on Nokia and Sony Ericsson devices, synchronization on Notes with Opera desktop version.
As a European user I don’t see it actually working any faster, but I hope it will be more stable. I really enjoy the skins because it allows to make Opera more like your current theme. Regarding YouTube the mobile version still doesn’t work on my E71. It starts Real Player but that’s all. Am I doing anything wrong?
