Email, Auto Send/Receive then Disconnect

[arparent]

I would like to have my mogul do Automatic Send and Receives with my Gmail account, but I'm fickle about battery life. I don't want it to connect, then leave my connection on all day draining my battery. Basically i would like to either have it connect, check email, and immediatley disconnect... OR, check email everytime I manually initiate a connection. I found a way to set a time limit on data connections, but I don't want it to hang up on me when I'm actually using it (i.e. streaming radio). Anyone have a solution?
