I'm having a problem where iTunes isn't updating my iPhone, or a co-worker's, to 4.2 for some odd reason. At home I get this message and she gets it at work: "There was a problem downloading the software for the iPhone "xxxxx iPhone:. An unknown error occurred (9006). Make sure your network settings are correct and your network connection is active, or try again later." We both have the iPhone 4 (4.1) 16GB models and iTunes 10.1. Any suggestions or ideas?
