I recently published an article on Enable Tethering On iPhone. After enabling tethering, I tested the iPhone tethering on my Windows Vista laptop with iTunes installed. It worked perfectly fine with the laptop, but when I connected it to the Desktop running Windows 7 without iTunes, the iPhone was not detected as the USB Ethernet adaptor as it did with my laptop.
In this article I will share with you how you can use iPhone tethering on any Windows computer without installing iTunes.
On reading through Whirlpool forums I leant that Apple has some special drivers which allow the iPhone to be used as USB Ethernet Adaptor. These drivers are by default bundled with the iTunes installer. This drivers is also known as the Apple Mobile Device Support (link at the bottom of article).
You can download the Apple Mobile Device Support Drivers which is about 15 MB in size, install it on your windows PC, restart the computer, connect the iPhone to the computer using the USB cable and you are ready to use iPhone tethering without installing full iTunes Setup.
TIP : Carry the Apple Mobile Device Support Driver with you in your iPhone, to do so follow this tutorial –Using iPhone As USB Pen Drive
