A growing trend I’m seeing lately is jailbreakers flocking to /r/jailbreak or other forms of social media to share their handset’s uptime. In essence, some jailbreakers appear to enjoy showing off their pwned handset’s stability, especially with regard to one jailbreak versus another.
One way to do this is to show off how long a particular handset has been running in a jailbroken state without needing to be re-jailbroken, as a longer uptime indicates that the handset hasn’t crashed or forcefully rebooted itself.
