Simple question people. I just bought the DX last week. This is my 1st smartphone and i've been doing a little reading about 2.1 and 2.2. Since i just got my phone last week, does that mean it has 2.2? or was it stock 2.1 and i have to update it to 2.2? sorry, i'm deffinitely a nub when it comes to this stuff.....and how can i tell which software version i have?
