Thanks very much.
The
default email package on my new T-mobile Samsung GS4
does have an SMS sync setting per email account--I assumed Aqua Mail must have the same. However, i see now the SMS sync setting in the default email package from T-mobile is phone-wide (I thought it was just a stand-alone app), or as beaky said--from the provider. Sorry, I'm a real novice, but I'm guessing this is why you root your phone and get rid of the provider junk.
