Is it possible to connect to a wifi connection that requires a certificate? At work, I'm able to connect to the wifi connection with my ipod touch, but i can't seem to get it to work with my Curve. Is it even possible (I'm using OS 4.5)

Yes, as long as you have the certificate. For my work connection I needed to sync the certificate using DM (installed with Certificate support) and then setup the connection.

Can that be emailed to me from my Admin?

Not sure. I've only done it that one way. I used certificate sync to sync the certificate to my BB.

you will need to obtain the cert from your admin. Then use DM to install the cert on your BB (you will need to do an advanced install of DM to choose the cert sevices options). Once this is complete, you can then configure your phone to connect to the wifi routers. All should work fine at this point. hope this helps
