FWIW, A friend of mine got his HW 3.0 upgrade on his M3P+ about a month ago and it was done at his house by a mobile Tech. I had a mobile tech at my house about 2 weeks ago for a spoiler replacement and asked him if he was also going to do my 3.0 upgrade and he said no, but they had been doing a lot of them recently, like 3-4 a week per mobile tech. He said it's about a 2hr job.
