My iPhone 3 won't sync to iTunes or charge when plugged in?

I've tried multiple USB cables and ports, reset my iPod and computer, I'm currently uninstalling iTunes and re-installing it… Any suggestions? It won't even charge. It makes a noise when it's plugged in but it doesn't do anything to the actual phone.

Same thing has been happening to me with my shuffle, and it says it needs to be restored but the conncetion is failed. My only suggestions are to check your manuel if you have it and go on the Apple website and read the troubleshooting guides, try whatever it says. I also un and reinstalled itunes and did all sorts of resetting and still, nothing works, but you have a differnent device and a different situation.
