I have a Droid phone with 3.5mm jack. I was getting the system update message every half hour and I was keep cancelling because I knew I would not like the android 2.2.1 version because I have had 2 previous Droid 3g that they were ruined by this update. Few days ago I was out shopping and my phone was hanging on my wrist and the system update message came up. Accidently the button to update was pressed and it started updating without me knowing it. This time I want to fix it by bringing back my phone to the previous android 2.1 version. Please help me. I don’t like anything about this new update. It drives me crazy that sometime I want to throw my phone out of the window. How to get my Droid back to android 2.1 version? Please help. Thanks.
