Bridge WiFi Via iPhone to PC

On a jailbroken iPhone 4 connected to WiFi running MyWi connected to my PC via USB cable, I was able to use my home WiFi connection to connect to the internet on my desktop PC (as opposed to connecting via 3G using MyWi as usual).  This would enable me to connect to the internet on my desktop PC using my phone (which doesn’t have a wireless NIC), while not using any of my cellular data plan.

To do this, I simply:

  1. Connected to WiFi on my iPhone.

  2. Connected iPhone to PC via USB cable.

  3. Launched MyWi on my iPhone

  4. Enabled “MyWi USB”

  5. Open “Advanced USB” menu.

  6. Set “USB Bridge” to WiFi

Enjoy!
