which app is this for, the one that is actually "GMAIL" or the one called "MAIL" that lets you set up a gmail account? Originally I used the latter and it has options within the app to set the amount of time it checks email, peak/off peak hours and such. It was pretty good. I have several gmail accounts for business or personal. My main gmail was listed twice under "accounts and synch" once for the actual gmail app, and once for the mail app. I got sick of looking at the same thing twice so I went to delete the gmail one and it said "do you really want to delete this account, deleting it will also delete all contacts, messages, data, etc, from the phone". So i said no and deleted the MAIL app instead and i dont like the format of the GMAIL app, it never notifies me of email unless I manual synch it, and dont know where the settings are to even change update times
