You may have heard about Personal Hotspot and wonder what on earth it is. First, get your mind out of the gutter. Personal Hotspot lets you connect your computer/laptop and other devices (up to 5) to the internet via the iPhone 3GS and iPhone 4. In essence, the iPhone is sharing its cellular data connection with devices that don’t have one.
I use Personal Hotspot to connect my Wi-Fi only iPad to the internet when a Wi-Fi connection is not available. I saved $130 by purchasing the Wi-Fi only iPad because of Personal Hotspot. No matter how much I adore my iPhone, the screen is small and given the choice, I would definitely prefer to stare at an iPad screen.
In Canada, there is currently no extra cost to use Personal Hotspot. However, you must have a minimum of 1 GB data on your iPhone plan (plans start at 500 MB). In the U.S., there is an added cost to use Personal Hotspot. Either which way, you still need to keep a close eye on your smartphone’s data usage, as you will feel the pain should you go over your monthly allotment.
Here’s how to setup Personal Hotspot.
