Hi there, I have a iphone 3G, using 3 email a/c on it. one is @mac.com, the other two is my companies' The problem I am facing is, when I get email on my @mac.com a/c, the phone will "ding" and notify me I got a new email. But when the emails are sent to my companies', there'll be no notification at all, I need to go to the inbox every five minutes to check whether there's any mails...it seems silly... I hope someone can help me out with this. thanks in advance.
