I have the original Motorola Droid A855 with os FRG83D 2.2.1. I had the phone successfully rooted and the wireless thether was working wonderfully with my notebook and ipad. About 3 weeks ago the os was upgraded from 2.2 to 2.2.1. Since the upgrade the wireless tether does not work. When I check superuser it saya I am rooted but when I attempt to run Wirerless Tether i get a message: "unable to start tethering". I also get basically the same message with Barnacle. Please help! Thanks beforehand..
