Tether is an application that allows your PC to take advantage of your BlackBerry® smartphone’s data plan, allowing you to access the Internet on your laptop anywhere there is cellular coverage from your BlackBerry®.
Tether use with my Blackberry. Love it. I have had it for several months now and used it no more than about 20 – 30 minutes at a time and probably used it around 3 or 4 times until this past Sunday. I signed on as we were pulling out of my yard in Pinetops NC in route to Durham NC around 95 miles away and I was on my laptop all the way there. It is fast too. I had all of these open: my email, my blog, Facebook and surfing the net and also received a phone call.
This week I have been going to my vehicle during my lunch break using Tether to check my emails, post on my blog and etc. I used to go to the college across from my workplace and sign on to the Technology Center wireless but now I am going to use my Tether more. Why not? It is a one time fee.
