iPhone 4 not charging or showing up in iTunes.
My iPhone 4 doesn't show up in iTunes anymore. It launches iPhoto but not iTunes. Also, it will only charge intermittently on an HP PC. When connected to any other charger, its home Mac or another Mac I get this message - "Charging is not supported with this accessory". I've tried several different cables and rebooting as well. Haven't updated iOS yet after hearing many horror stories from people who did with older iPhones.
iPhone 4, iOS 6.1.3
