It will, but there's a compromise in terms of reliability since you're counting on a desktop PC to be up and running. If anything happens to that PC, no email gets forwarded to the handheld.
I just got a 7250 on Sprint and all I do is forward a copy of all my email to my blackberry address and it works great. I like the fact I do not need to rely on software running on my computer. I had this with Sprint's Business Connection it was ok but it really sucked when it did not work since I had no way of getting it restarted.
