There are many applications on the AppStore that allow us to access our Mac and PC directly from the iPhone.

For those who need access to your PC / Mac even when you are away from home and 3G network, we have many choices available. Some of these use the HTTP protocol (ie with vnc proprietary applications), others use the vnc protocol (which will need a router side configuration).

We iPhoneItalia we tried to select five of these applications and to compare them in a unique video.

The video is of iPadItalia in this article.
Enjoy it.
