When it comes to Android crapware, AT&T's light-touch policy means that the new Moto X is already offering a close-to-stock experience. If, however, you want to be doubly sure that you're only getting what
God Motorola intended, then the Pure Edition is likely to be the device for you. According to The Verge, the phone company will offer its homegrown equivalent to a Google Play Edition device on its store towards the second half of this month. Is it true? Probably, but that doesn't mean that we haven't reached out to the company for more information, and will update this to let you know what we find out.
Update: Motorola have confirmed that the Moto X - Pure Edition will be coming, but declined to mention when it'd be arriving.
