any Virtual Ipad/Iphone applications for PC that has network connections?
As there are no emulation / simulation engines that I've seen that work well enough to run tutorials in anything resembling a smooth manner, your least expensive option would be to get a cheap secondhand iPad and then use AirPlay emulation software on the PC to capture the screen and make your videos.

You could even save money by taking static screen captures and then animating them on the PC.

The only simulator that even comes close to what you need runs on OS X and is part of Xcode delivered from Apple. You could probably virtualize that, but the cost there is more than buying cheap used iOS hardware. Even an iPod touch is often good enough for walk through videos on basic settings for corporate users.
