if you’re really concerned about your mobile Internet security, consider using a Virtual Private Network (VPN) on both your Wi-Fi and cell data connections. When connected to a VPN, all your Internet traffic travels through an encrypted tunnel, guarding it from local eavesdroppers. It protects your traffic and passwords not already encrypted and also gives encrypted traffic double encryption. In addition to encryption purposes, VPNs can also give you secure remote access to files and network resources at work or home.
iOS -- iPhone, iPad, and i-pod touch -- and Android are two popular mobile platforms that include native VPN support. Most other platforms include some type of VPN functionality but usually require you to have a special server in addition to a VPN server.
For devices that support regular VPN connections, you can use a VPN from work if they provide one or setup your own VPN server at home using Windows or a third-party server. You can also use hosted services, such as from Witopiaor try free services: Free Shield VPN or Hotspot Shield.
Remember, encryption is the key to securing your Wi-Fi traffic. Use HTTPS/SSL encryption, try to use secured hotspots, or avoid hotspots altogether by using the data plan. If your device supports VPNs consider using it.
Wi-Fi is only one of the many security concerns you should have about your mobile gadgets. Remember to also regularly backup your device and set a lock-screen or device password. For the best security, consider a mobile platform that has full device encryption, such as iOS or BlackBerry. This will protect the information stored on it from even the most determined hacker
