VyprVPN iOS - abibility
I just "deactivated" VyprVPN iOS on my iPhone 4S because often I had the problem that I had not been able to connect to internet because it seems that actual VPN server had a problem. 3G mobile internet and provider connection had been good. But this sucks... Ability to swith of VPN in this situation would be useful but everytime you start Safari Browser, Mail pulling, Whatsapp VPN is starting automatically.
The 2.1 release add much increased stability to the connections. Please try it out and let us know if it resolves your issues.
