It looks like Apple is planning on releasing a new web based diagnostic tool for iOS devices, according to a recent report from Hardmac, and the new tool could be used by Apple technicians to diagnose problems with Apple devices remotely.
This would enable Apple to potentially fix any problems with your iOS device over the phone, without having to actually take it into an Apple store fr it to be fixed.
Apple announced (internally) that they have put the final touch to the tools that will facilitate a diagnostic. It will be simple to use and can be used remotely. In effect, this systems operates entirely online. An email is sent to the device containing a URL (this can also be entered by hand) and the device will connect via Mobile Safari and the telephone to start internal checks and sends the result of it to the Apple servers to which the service centres are connected.
This could end up being very useful for both iOS device owners and also Apple, as it would enable them to fix many problems over the phone, which could save you a trip to the Apple store to get you device fixed.
