When AT&T recently started sending out warnings to people who were carrying out unauthorised tethering on jailbroken iPhones using their network, many questioned just how AT&T were able to detect who was getting free tethering on their iPhone in this way. Well now a report on Android Police has shed some light on what would appear to be a problem unique to the iPhone, as there has yet to be a single case reported of AT&T sending one of those warning text to an Android device user. According to Android Police, jailbroken iPhones use the same tethering method as iPhones that havent been jailbroken, which is already part of iOS. This has the advantage (or disadvantage, depending on how you look at it!) of enabling AT&T to identify when any iPhone is using tethering, because when doing so it sends traffic via a different APN, namely an AT&T access point or router, simply so that AT&T can ascertain what part of the traffic is tethered data. In contrast, Android Police explain, Android tethering is not set up to be re-routed this way, so AT&T would have to scan packets to find out who is and is not carrying out unauthorised tethering, which they are unlikely to do because of the costs involved.
