Here is remote control Apps for iPhone that you can use.
1.WiFi Remote
WiFiRemote is a 8-in-1 wireless remote control with a decent range of features. These include a multi-touch trackpad, text-pad, landscape keyboard support, an accelerometer mouse and various media players. If you can look past the dated interface, it works pretty well. Download this App.
2.Apple Remote
Available completely free from Apple, the Remote app allows you to control an impressive range of iTunes features. Navigate between songs and videos, view artwork on your device, and alter settings – all from the palm of your hand. It plays great with AirTunes too. Download this App.
3.Air Mouse Pro
Air Mouse Pro is both a fully-functioning trackpad, “air mouse”, keyboard, and remote control for media playback. A really innovative use of the iPhone’s accelerometer to move your cursor around the screen. Download this App.
4.Remote Jr
Remote Jr will either work as a simple remote control when in portrait view, or display a full interactive version of your Mac desktop when tilted sideways. Functioning over Wi-Fi, 3G or EDGE, you can also customize the colors of the remote control display. Download this App.
5.Remote Tap
Remote Tap is a great VNC app (one which shows your desktop in real-time), which can also swap between spaces, multiple displays, and act as a control for Front Row. The list of features is very, very thorough and I’d recommend visiting their site to take a look at everything on offer. Download this App.
