Nope. Some GM's do consider it cheese, though - not so much technomancers in particular using it, but rather the software as a whole, since it's sufficiently cheap that it basically amounts to "+6 dice to all social skills for anyone who gives a damn" and ultimately just results in everyone rolling 6 more dice. Of course, technomancer faces can easily enough use it to get 12 more dice and thus come out ahead of everyone else.
So, if your GM allows it, yes and you do totally want it.
