I found an iPhone software that can let you access your remote PC from iPhone. It is very easy to use. No hardware requirement, no firewall settings, no router configurations, no ports need to be opened. The most important is it can be free download and install. Below is the step on how to use it:
1. Visit
Gooer Remote Desktop Service and create an account at
Gooer Remote Desktop Service. During registration,you need input your correct and valid email. The email is case sensitive.
2. Download Gooer Host Software(
http://www.gooer.com/download/Gooer_RDP.exe) and install it on the PCs that you want to remote access.
3. Install GooerRDP from AppStore on your iPhone/iPod You can also install GooerRDP using installer or Cydia.
4. Start GooerRDP program and access your remote PCs. (The website on
Gooer Remote Desktop Service can only use one week for free, you can register another account and continue use it after one week.)
