iPhone 3G and 3.0 Software Update

I upgraded today, with a couple hiccups.

First off, when it finished the upgrade, it said something about not being able to read the SIM properly. Then, it has decided to give me the most interesting of error windows when trying to view the iPhone window (the one wherein you can set your iPhone preferences).

Seriously, what gives?

Everything is working ok now. I'm pretty sure that it was just a large amount of traffic screwing things up somewhere...
