VPN For Nokia
We strongly recommend 12VPN for Nokia users. 12VPN makes getting a VPN for your Nokia phone quick and simple. Nokia N900 can directly use OpenVPN which can be downloaded at the 12VPN official site. Most other Nokia phones, including Nokia N8 have to download mVPN from the Nokia site (free), and then can use the 12VPN service.
mVPN uses IKEv2, but really, you don't need to know all that. Once you sign up with 12VPN, you get access to special “Nokia Page” which will take care of all the formatting and set-up of protocols is done automatically.
