When I first started jailbreaking many years ago, it seemed like tweaks for modifying the carrier details in the Status Bar were a hot commodity. Given just how much times have changed, you really don’t see tweaks like the classics anymore.
The new Signal jailbreak tweak by iOS developer Sniper_GER is a blast from the past, as it lets you spoof the Status Bar’s cellular information on any jailbroken device whether you have service or not.
