Not a lot of changes noted. The dialer pad is different (see below), but other than that haven't noticed much else. Continuing my soak test for the rest of the week. By the way, even though this is for T-Mobile, as long as you aren't rooted, but have an unlocked Moto X (I.e. no carrier branding), this update can be downloaded and used even if you are using an AT&T Sim. Doesn't effect the phone.
