In computer, VNC or Virtual Network Computing is a graphical desktop sharing system that uses the RFB protocol to remotely control another computer. Same thing can be done with iPhone (Jailbreaked) with the help of Veency, Veency is a free app developed by Jay Freeman Saurik, Mind behind Cydia. Veency allows iPhone owners to remotely control their iPhone from the comfort of your PC or Mac desktop via a VNC client. All you need is to install Veency through Cydia or ICY and then restart your phone. You won’t see any new icons, but your iPhone or iPod touch can now accept VNC connections. You’ll need a VNC client to connect to your device. Windows users should check out UltraVNC or TightVNC, while Mac OS X users have the excellent Chicken of the VNC.
How to Install & Use Veency for iPhone :
1.) First of All install Veency from Cydia or ICY and reboot or respring your iPhone.
2.) Head to the home screen and then to the Settings tool. Click Wi-Fi, then the arrow to the right of your home connection, and note the IP address listed there.
4.) Open your client, enter the iPhone or iPod touch’s IP address as the host, then pick up your device. You’ll see a prompt to accept or reject the connection from your computer’s IP address.
5.) Hit “Accept,” and you’ll notice a small VNC icon in the upper-right, near the battery indicator. That’s it.
Use iPhone mods and hacks at your own risk! Installing 3rd Party iPhone apps requires you to jailbreak the iPhone before installing the native software and apps.
