Well, kind of. I was actually going to post this topic last night when I got my first facebook push notification after several days. I got a few more, but when I woke up this morning, I've stopped receiving push notifications again. It's not working with my ESPN application, either. It's not a huge deal, but it's mildly annoying. I do have the push notifications turned on in settings under "Notifications", have the phone set to push under "Mail, Contacts, Calendars," I've turned on the notifications in both the Facebook settings and in the Sportscenter application. I am running 3.1.2 and I did my jailbreak using Pwnage Tools. I also am on the AT&T network. Is it possible that some of my other applications are stopping the phone from receiving the push notifications?
