Seems like after the gingerbread update I'm now missing the "silence all" mode from where you hold down the power button. So how the hell do I silence everything with that now missing??? And the phone reception stinks!!!!!!!!!!!!!!!!!!!!!!!!!!
Thats strange that this feature was removed, well as a solution you can concider downloading Audio Manager from https://market.android.com/details?id=com.smartandroidapps.audiowidget&feature=search_result .. This allows you to create a profile for audio and plave it on the desktop to trigger the profile..
