I have a My Touch 3g 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’ve had 2 previous my touch 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 2.0 version. How can I get My Touch 3G back to Android 2.0 version? Please help. Thanks.
