Somewhere along the way I think I've screwed up my iPad 3G's APN configuration (the field where you tell it what carrier you're connecting to.) And in 4.2.1, this field is now hidden (which is kinda rude, considering the iPad is sold "unlocked.")

Anyway, I'm able to work around it with a Cydia hack called "APN Switcher" -- but it's a pain in the butt. I'd like it to work the way it's supposed to. I've found the file I need to clean up, but I don't know what the original settings were.

Can anyone with a jailbroken 3G iPad running 4.2.1, that wouldn't mind taking a look at (or sending me) the
System/Library/Carrier Bundles/iPad/ATT_US.bundle/carrier.plist
file get in contact with me?

It'd be much appreciated.
