I almost posted this in the iPhone forum, but then realized it wasn't an iPhone problem, it's a laptop problem. My iPhone 3Gs running firmware 3.1 will not sync with my iBook g4 running OS 10.4.11. I have the newest available versions of both iTunes and Safari. The phone WILL sync with my wife's Macbook, so I know it isn't the phone. I am stuck with the iBook for now, because my house was burglarized and my Macbook Pro was stolen. Thanks in advance for any help.
