There was me thinking everyone fell asleep at Yahoo! headquarters. It seems they have reportedly fixed the huge IMAP issue that has had people using more data than they should on not only Windows Phone 7, but iPhone too. Just in time for the pre-NoDo update, oh... maybe not.
Rafael Rivera kept an eye on the Yahoo connection as to whether or not they would update their "imapgate" software. Today, he "was pleasantly surprised to see they had upgraded from 0.7.65_12.286037 to 0.7.65_14.298026 fixing the issue." While he can't comment on the exact millisecond the update was published, Rafael suspects it was rolled out earlier this week.
It’s nice to see Yahoo! fixing problems that arise, although I suppose I’m just an insensitive badass sat on my podium with my shiny ActiveSync account. Are you a Yahoo! affected customer? If so, have you continued to experience issues with data usage today with access via IMAP to your account (should you monitor your traffic)?
