I used Freedome by F-Secure. They have smartphone apps and support Windows/OSX. It's fairly inexpensive, run by a security company, and they don't keep logs.
As far as I know there is no notice about logs on their website? Also, this forum post from January makes me struggle if the system has been audited already. But nevertheless, most of VPN providers aren't audited or at least do not publish the audit report and Freedome is very new to the market, so let's see.
http://community.f-secure.com/t5/F-Secure/Does-F-Secure-follow-the-EU-data/ta-p/68996 "F-Secure does not retain any kind of data or log users’ traffic." I should say, I'm not claiming that Freedome is the best VPN in the world. I use it and trust it, but I'm not in a life-or-death situation when it comes to sharing content. If life-or-death describes your situation, please please please do more homework than I have done trying to pick a VPN provider. My main concerns when it comes to VPN providers is "do they log", "can I pretend to be in another country", and "will they encrypt my traffic". That's it. Don't take this advice if your life depends on your anonymity.
