How to disable alert badges for the iPhone Mail application (iOS4 )?
What I've done is disable "Push" for Mail. In this way, I just get new mail when I enter into the Mail application and also rejuvenate it. It reduces both disturbances and also battery life.
In Settings > Mail, Contacts, Calendars > Fetch New Data, I set Push to Off and also the regularity to Manually.
Turning on/off badges/alerts/sounds alert for each and every application is currently readily available generally setups on iOS 4.
Nonetheless, this is just for 3rd event applications. Switching off badge alert for the Mail application is not feasible presently.
