Does Boxcar push over wifi when 3G or Edge is unavailable?

Hi
I'm a new user here. I'm trying to use Boxcar to push announcements from google voice. Where I work I have no cell service but have fantastic wifi. But firewalls do not allow apple iphone mail or mobileme push features through. However, http traffic is as it should be allowed to pass. So reading gmail at work on my phone means using the gmail/safari interface., with, of course, no push.
Since I've set up google voice I am looking for a solution for the long-standing problem of people not being able to contact me when I'm at work via phone (I'm talking family here, emergencies and such). Enter Boxcar. I forward pertinent gmail notifications from google voice to Boxcar's address and hopefully receive the notification on my phone. If . . . . Boxcar works over wifi and specifically sends traffic through port 80 or 8080?
So does this work? I'm not at work for another week and quite frankly can't find any other place where I have wifi but no 3G. Nor can I turn off just cell support on my iphone while leaving wifi on. So there is no way for me to test this for a while. Hence this question.

Hey David,

Apple sends push notifications over port 5223 (via TCP).
Boxcar itself uses HTTPS (port 443) to load your inbox and communicate with the Boxcar servers in general.
Sadly, I think that doesn't leave us with many options. I wish there was a way to adjust the push delivery port, but that's way beyond what Apple allows us to do.
I do wonder though if you setup a VPN with your home computer (or something similar), if your device would route push traffic through that as well.

Wow. Thanks for the fast response. Port 443 is open I believe since we
do recieve https traffic. It may work.
Otherwise I will try the other route. We do have port 22 open per my
urging so. I should be able to tunnel the 443 traffic over ssh to port
80 using a home computer. I just hoped to avoid yet another link in
the chain. This is encouraging.
Thanks again for your response.
