I don't know what's going on. PUSH email on my iPhone was working properly, then suddenly I noticed no more email were being pushed. I found out because I had to MANUALLY check emails on my phone and until then it would download any pending messages. I've reset the settings again and again to "PUSH EMAIL" and things don't change. I still have to manually check my emails. Have you guys had something similar happen to you? Is it a phone issue or a AT&T issue? Thanks for your replies.
