Even though I have been using my Google Nexus One for tethering (portable wifi hotspot) for a while now, one of the annoyances was having to go into the menu structure to turn it on.
Menu -> Settings -> Wireless -> Portable Hotspot -> Turn it on….
There didn’t seem to be a quick way to add menu items to the screen. You couldn’t add it as a shortcut either.
After doing some of the Google stuff, I found that there was a free widget I could download that would then give me a widget on the home screen to turn the portable wifi hotspot on and off with a single click. Result!
