Android OS 2.2: 3G/WiFi Tethering – One cool feature!
One of the coolest new features in Android OS 2.2 is its ability to share its 3G wireless data connectivity with other devices. It can do this by either connecting a USB cable to the phone and the shared device (typically a netbook or notebook computer) or by creating a WiFi Hotspot.
That is very cool. No more need for buying into wifi connections at hotels, coffee shops or paying for one of those expensive USB connect cards.
