T-Mobile issued a stern warning to its customers against downloading and installing the new iOS 10 update to their existing 6, 6 Plus and SE iPhone models. According to the T-Mobile website, doing so will, cause the handset to “lose connectivity [to the T-Mobile network] in certain circumstances.” Once that happens, the user can only re-establish their network connection by fully powering down the phone and restarting it. That said, the company does expect Apple to push a corrective patch live within the next 48 hours.
