Just got my Galaxy S3 (ATT) And set up the G Mail app and it works great, TOO great as in waking me up in the middle of the night because Bike Nashbar is having a sale. I want my messenger notifications to push and sound. But NOT my mail, I will just load it when I'm ready to read it. Do I have to un install the G Mail app, and just run on a browser? or can I configure it to NOT push?
