Here's a weird one.

It appears that I can't add or delete anything but wireless connections in Settings in the Internet Connections area. I have something I called GPRS ipv6 (that's the name I gave the connection) and one called T-Mobile Internet. When I highlight either of them, Delete is grayed out. If I try to add a new connection, I can choose Wireless but not GPRS.

I don't think this was the case before I updated. My connection with the label I created, GPRS ipv6, won't work today. It was working yesterday.
