Real (read: free tethering) and truly unlimited data are soon to be extinct. This is a given. However, as for how carriers spy on users and determine exactly how they consumer their data has remained a mystery. The general consensus is that cellular carriers will go off of bulk data usage along. But a brief account by Alex over at iPhoneDownloadBlog sheds some new light on the free tethering cat and mouse saga.
After Alex received an alert from AT&T about tethering — he uses the popular MyWi — he decided to give AT&T a call and play dumb. In short, his fact finding mission netted him some potential damming evidence concerning iOS 4.3.3. According to the AT&T rep Alex spoke with, iOS 4.3.3 contains several new security/bug fixes that plug some “illegal” tethering loopholes. While we haven’t heard of widespread broken tethering after upgrading to iOS 4.3.3, we must admit that most of the people we talk to whom also jailbreak wait until the latest jailbreak is available before upgrading.
