When I launch iTunes (with my iPhone attached), and click on "check for update", I get the error message "iTunes could not update the carrier settings. An unknown error occurred (OxE800003D)". My Internet is active and I have the latest 3.1 software on my (3GS) phone and iTunes 9.0.1. I've tried deleting the deleting the carrier settings update file (/Users/Username/Library/iTunes/iPhone Carrier Support/) I also reset the "Network Settings" on the iPhone (Settings>General>Reset>Network Settings). I still get the same error when attempting to update the iPhone Any ideas?
