Android 4 don't require unlock at home In the Android OS version 4, what would I have to do to require a pass code to unlock the phone when I'm away from home, but when I'm at my home, I don't need pass-code restrictions.

Detecting proximity to my office could be done by detecting a WiFi or BlueTooth link to some hardware in the office, but GPS would be iffy since it doesn't work well inside. Also Google's location service would work, since it seems to know where my WiFi router is located very accurately.

I would also be interested to know whether this would be compatible with the full storage encryption on the Android.
Skip lock screen (formerly "Unlock with WiFi") will let you bypass your device lock screen if you are connected to your home WiFi network. (Or whatever WiFi SSID you define.)

I used it a year or two ago and it worked well.

There is also a trial version.
