Google finally added the T-Mobile Hotspot Connect to the Android Market, and not a minute too soon. Now you will be able to use your G1 to connect to any T-Mobile Wi-Fi hotspot for free saving your battery from the strain of using 3G.
You can find T-Mobile Hotspots in many places including coffee shops, hotels and airports with more added all the time. You can use the hotspot for anything from surfing the net and sending instant messages to connecting to your corporate network with confidence on a completely secure network. I personally do not know anyone who actually uses this feature. I can imagine it coming in very handy in times when coffee shops charge you for internet use. To date I only know of one place that actually has a hotspot, who knows of a local hotspot that they will be using regularly?
