I have a OS X 10.4.11 and my new iphone 4 will not sync with it. I get a message that says i need a 10.5 or higher. what can I do?

The only thing to do is upgrade your operating system version to 10.5 or higher, as your computer permits.

Start with getting more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac", then "More Info..." Copy and paste the information here, but omit the serial number and Hardware UUID (if present). Compare it to the requirements for each system version below, and we can also provide guidance once we know what computer you have.

Snow Leopard 10.6 Technical Requirements - http://support.apple.com/kb/SP575

OS X Lion Technical Specifications - http://www.apple.com/macosx/specs.html

See this user tip to see if you are ready for 10.5 or higher:
