iPhone won't sync with iTunes anymore
I'm not sure what happened, but iTunes won't sync with my iPhone 4 anymore at all. I changed my DNS server settings on my Mac and iPhone (because of stupid Comcast) and now I can't sync using wifi or usb. I reverted all my settings to how it was before and it still doesn't work. I'm all out of ideas and its starting to **** me off so any help at all would be GREATLY appreciated!!!
iPhone 4, iOS 5.0.1
