I posted a thread in the general iphone area but since than i have done some trail and error and i pinpoint the problem. So with backgrounder install push email will work one when the mail.app is not running. after you open the mail.app to check your email it will no longer push in the background if you have the app off. It will only push if you leave the mail.app running in the background. I try all the setting in backgrounder and it is still like that. Uninstall backgrounder and push email is working perfectly fine. Anybody else?
