Just now I shared how you can enable (wired) tethering on Nexus One, and here’s another similar tutorial to enable wireless tethering on Nexus One.
In my opinion, wireless tethering is always easier and better to set up than wired tethering as you don’t have to keep your phone connected with a USB cable.
Tethering is one of the first features we try to get when we get a new smartphone like the iPhone, Nokia phones and now the Nexus One. I have previously shared how to enable wired tethering in HTC Hero.
It was easier on the Hero as it comes out of the box on Android 1.5, but you will require to go through some steps before you can enable tethering on the Nexus One too.
