A friend of mine got an iPhone 4S a few months ago and had it jailbroken, it was working fine up until recently. The issue is that his charging dock connector is broken and only charges when the phone is off, he is unable to connect to iTunes or even get the computer to read it as a device. Since it is jailbroken, he can't take it in to the Apple Store to get it repaired or even checked out. We have attempted to update it over-the-air, but apparently there is a block that prevents accidental upgrades/restores while jailbroken. I was hoping someone had an idea of how I could go about resolving this issue, more specifically if there was a method to bypass the block that prevents upgrades/restores or some other means to fixing/restore the phone so that it can be serviced by Apple. Thanks!
