So until today, my iPhone 3Gs worked with iTunes and was appearing on the devices list. However, I updated iTunes & Quicktime and now it's not being recognised. The USB connection sound can be heard but nothing appears in iTunes. Currently my iPhone has the iOS 4.3.5 and iTunes is 10.4.1.10. Can anyone help me with this issue? I'm not experienced in fixing such things. [eta]: If it helps I've uninstalled iTunes, Quicktime and the related software and re-installed them to no luck. I then found out that my Apple Mobile Device Support won't start. I can't even restart it, when I click it it comes up with an error saying... Windows could not start the Apple Mobile Device service on Local Computer. Error 1067: The Process terminated unexpectedly Also if it helps, I'm using Windows 7 (64-Bit).
