I had been wanting to get a Zmax Pro for a while because of his many times I had read about what an amazing deal it is supposed to be. I finally got one and now I'm reading about bugs, firmware issues, and a lack of rooting ability if that is your thing (I've never done it but always liked knowing I could if my phone irritated me enough). I have the b20 software, which I'm hearing is a bad thing. Did I make a bad choice in getting this phone? Should I get the b21 update? Anything else I should do or not do with my phone to keep it running well?
