Both my roommate and I go to Providence College and we have the same problem. We both work for IT as well and have had several conversations with our Network (and Server) Admins to no avail. From what we can tell other than the iPhone no mobile phones are able to connect to our secure network. It's not that big of a deal for me b/c i have 3-3.5G Tmobile but my roommate is on AT&T and really wants wifi while we're at work. If anyone has any ideas that would be great.
