Blackberry owners are all probably more than familiar with Tether, which is turning one year old this week (check out their one year contest, in which they are giving away six brand new phones).   In addition to that giveaway, though, they also announced they are branching out and offering their service to Android users.   For those of you who are not familiar with it,Tether is an application that allows your PC to take advantage of your smartphone’s data plan, allowing you to access the Internet on your laptop anywhere there is cellular coverage.  Until now, this service had only been available for Blackberry…until now.  Last night,I received an email from the folks at Tether announcing that their new Android app is now available to Beta testers.  According to them, the Android tether app is already marking speeds up to 6.8 Mbps.  head over to Tether to sign up for the Android Beta.
