I just installed the VIP theme and I can't figure out how to change the weather settings to show my current city on the wallpaper. Any help would be appreciated.
There's usually two ways that themes get weather info. The first (and easier) is by drawing it from the built in Weather app. Make sure you've added your city to the stock iPhone app, and that it's the first one on the list. (Not Cupertino or some other city.)
The second way is a little more complex and involves getting a weather code from Yahoo and changing the html file in the theme...try the first way and report back if you're still having trouble.
VIP might be a little different (I've never used it) but the basic idea should be the same as this:

Good luck!
