I have a 3G, 16GB iPhone. The problem I'm having is thus...


I have set up my Mail App to check my Yahoo email account, but about after a week it stops checking my email. Now I can actually go into the Mail App and see if I have email but it stops showing the red circle with the number in the middle of it of how many emails I have on the Mail App on the desktop. The only way I know to fix this problem, all be it temporarily, is to go into my settings, delete my Yahoo email account, then re-enter my information and it will be good for another week or so. But I shouldn't have to do that.


So, why does my iPhone stop showing the number of emails in the red circle on the desktop after so many days? I haven't and don't change any Push settings what so ever. Push is set to ON and Fetch is set to Manually.


PLEASE HELP ME!!!
