While giving the AT&T HTC One X's firmware a look over, I ran across a a vulnerability that would allow us to gain root access. It turned out not to be all that useful at the time, as another root was released the same day. With the latest 1.85 firmware leak, the previously published root has been fixed, making the one I found earlier useful once again.
Update: AT&T disabled the app installation features of Ready2Go thereby breaking this root process. We don't have an updated root method at this time.
This vulnerability happens to be in carrier bloat - specifically an app called ATT Ready2Go (also know as dashconfig), which is shipping on many new AT&T LTE devices.

Two weeks ago, Google announced a series of expansions to carrier billing options for Play Store Apps, Movies, Books, and Music on various carriers. While some changes went into effect immediately, Sprint, which already allowed direct billing for apps, was one carrier that was listed as "coming soon."
As of today, all three additional options are available to Sprint customers: books, music, and movies. Not surprisingly, carrier billing is the default option since it's by far the cheapest to carriers and Google as they get to bypass credit card fees. While this addition doesn't benefit everyone, I can see a few handy uses for carrier billing:
- you don't own a credit card at all
- you don't want to add a credit card to your Wallet account for some reason, be it security, paranoia, or a medical condition that prevents you from typing 16 digits in a row (also known as laziness)
- you don't want to pollute your credit card statement with multiple charges
- you don't want your significant others with access to your credit card statement to see what you're doing

It seems the explosive growth of smartphone use has had some unintended consequences: U.S. carriers are moving towards tiered data. While some carriers have had "soft" caps for years, we've recently seen a move towards hard caps. "Tiered" plans have long been standard in other parts of the world, but the simple difference is that US carriers charge significantly more across the board - be it basic plans (just minutes), add-on's (such as texting), or data (whether used on a plan or as-you-go).
