I have a Verizon iPhone set up with my Yahoo! email account. I have the premium service, mail plus, or whatever they call it. I also have the mail setup for push. Here's my issue: Every now and then, I won't get new messages until I go into my mailbox - as if I had it setup for fetch. Now, what's the point of having push available if it won't push? Is it an issue with Yahoo! since they recently changed their servers? (because of the whole Windows phone issues?) Or is this an iPhone server issue?
