Snapchat has apparently abated from its cat and mouse game with jailbreak tweak developers. Less than a few days after Snapchat begun locking out users who had Snapchat-specific jailbreak tweaks installed on their devices, Snapchat stopped locking out users.
How long will Snapchat stop its lockouts? Is this just a temporary thing until it's able to adequately update and clarify its terms of service? It's still relatively unclear at this point.
What is clear is that Phantom, a Snapchat-centric tweak created by jailbreak developer CokePokes, has been updated to workaround the Snapchat crackdown. So even if Snapchat were to change its course again, and reengage jailbreak users, Phantom's latest version should work regardless.
