Snapchat is locking users who have Snapchat jailbreak tweaks installed on their iPhone, iPod touch, or iPad. If your account is currently getting locked out of Snapchat, chances are you have got a jailbreak tweak such as Phantom, GhostPref or SnapMoreText running. The application now detects for jailbreak tweaks specifically used to breaks Snapchat features and/or adds more functionalities to the app.
For example, if you have Phantom for Snapchat tweak, you’re allowed to disable Live Stories, screenshot without notification, play a Snap for unlimited of time, and much more. According to CokePokes, creator of Phantom, he tweeted out today. In the future, there might be a way to bypass this.
