Free “Push” based mobile email delivery company emoze is challenging the BlackBerry to another Showdown at the CTIA Wireless 2007 conference next week in Orlando to see who’s “Push” based email delivery system is the fastest.

In the first showdown, emoze beat the BlackBerry thumbs down. My guess is that emoze will win the speed test a second time, however, like I said the last time, it probably won’t mean much if it does.
