I got an e-mail from someone at Sprint yesterday asking me to pass along this information, which I will gladly do.
Of course they're doing it for good PR and marketing, but does that really matter? Anything that helps people (and doesn't hurt other people) is good, even if there is an ulterior motive. Good on Sprint for doing the right thing and helping poor folks in Michigan. The program has already launched in Tennessee and New York, and they're planning on expanding the program to other states too which is great.
