Guys, I'm at the end of my tether. My iPhone 4 is virtually a brick after having upgraded to iOS 7. I'm desperate to see it back at 6.1.3, but don't have a Windows PC at my disposal. So - can iFaith run on Parallels? I'm running a build of Windows 8.1, and when I start up the iFaith .exe package, it tells me 'the network name cannot be found'. It gives me the option to click 'continue', but nothing happens when I do. Help?!
