Boy Genius Report y AppleInsider
This would be done from a web page whose link we would receive by email, and therefore there would be no need to install any native applications.
Such a diagnosis would be able to collect comprehensive data on the state of the device’s battery (charges, current charge status, time since last charge and minimum charge level at which we have put the phone), the version of iOS we have installed, if the device has been turned off correctly… basic data that can lighten the diagnosis of the problem saving time and even trips to the Genius Bar .
What about the privacy of all that data? According to the source, Apple will only ask for the UDID number (a unique identifier) and the customer’s name. It is already commented that this diagnosis can take advantage to look for a jailbreak in that device, and it would not be strange seeing that in the Apple Store they cannot offer assistance if they see an iPhone with one of those patches applied.
On the other hand, a job offer at Apple has aroused the curiosity of the media: an engineer specialized in location technologies is wanted to “work on promising new developments in location services for iOS” . At this point I don’t think we’ll find anything new in iOS 5, but maybe Apple has an ace up its sleeve for the next updates.
