Im new here, first Android, Hero, flashed to Metro PCS 2 days ago. I can cancel past it and everything seems to work fine. I wifi only, never tether, no 3/4G. Read on another thread from a year ago some other various fixes including the previous. I'm worried about resetting what ever Metro did if I follow any of these instructions to fix error code 67, and losing my "telephone" in the process. Any thoughts ? Thanks
