Have been an iPhone user since the 2G launched, now that internet has be a vast cloud, with things like cloud storage, online shopping & payments and what not, is it safe to just rely on the phone security or security patches that comes with firmware update. Recently, my friend told me about how he uses a VPN service on his iphone 24/7 while he is over the web. So now i want to know how do use a service like that on your phone and which service should I go for.
