Tonight, after 2 months, my Yahoo PUSH mail finally started working as advertised! It's a night and day difference, and very fast. Maybe Yahoo finally started feeling the heat from GMail when they added IMAP and gave the iPhone servers the power they need. Anyone else experiencing something similar?
NEW UPDATE: Well, this morning PUSH was back to it's normal, non-functioning self. But I tried something that got it up and running again. I went into the Mail settings, turned off Push Mail, exited, then reentered and reactiaved it and it's working great again! Perhaps the problem is with the iPhone firmware, or even AT&T. Warning: Doing this seemed to make some week old emails come back from the dead. I don't know if it is related.
