Hi, I am petty sure many of you facing the same push notification issues which sometimes it working perfectly and sometimes it don't. It works when you reboot your iPhone or the notification will alert you when you open the application (IM Chat especially or mail). I searched and read some of the forums, some people said it happen since iOS4, which I am not really sure. But what I know I had this issue quite sometimes and right now I am trying on iOS5 Beta 7 and I still have this issue. I guess Apple didn't fix it. They just did a cosmetic touch up on the look in notification center. Anyone know is there any third party app able to do the trick?
