Q9m Noob! Hey guys. As you can see, I'm totally new here. I am buying a Q9m from someone on Craigslist. I am just wondering if there is anything good to know or "secret" I should know about this phone? One specific question I have is what does a wifi miniSD card do for the phone? I will not be getting a data plan, so would this allow me to use email and internet without paying for it? Please explain. Thanks! And give me any advice that you want.
