Not sure about other carriers but with tmobile and the BIS account... i can log into MyTmobile and under the e-mail managment link, clicking the filter button i can choose whether or not to forward e-mails to a specific e-mail account and leave others on. So when i am at work i turn it off because i dont need to see those until i leave, which is when i turn it back on. I am able to keep the others on so i can still recieve home e-mails at work and dont need to turn data off.
