Yeah I got mine for free, didn't even have to haggle with them. I get a questionable single bar of signal in my house and it has helped me greatly. I have all kinds of issues with MMS and even text messages, delayed messages, refuses to send MMS at times, etc. It's also a major pain into that my GPS doesn't work until I'm several blocks away from my house because it still thinks it's connected to the Microcell.
I can't wait to get rid of it, I'll probably smash it with a bat like in Office space.
