Answer 1

Actually you can use config.xml to set it to all devices if you're using PhoneGap Build...
Set the propertie: orientation with possible values default, landscape, or portrait
example:

< preference name="orientation" value="landscape" />

*please note that default means both landscape and portrait are enabled.
