Difference Between Tethered and Untethered Jailbreak (With Table)

Every person who possesses an iPhone but wants their mobile phone to be free from the various restrictions set by Apple can get their mobile phone jailbroken. Jailbreaking is the process and mechanism by which an individual can modify and update their iPhone’s software by voiding the warranty of one’s mobile phone.

Tethered vs Untethered Jailbreak

The difference between tethered and untethered jailbreak is that tethered jailbreak helps in removing the set restrictions in an iPhone by connecting the iPhone with a computer and then by booting it using the jailbreak software. On the other hand, the untethered jailbreak effect is stable, due to which an individual can reboot his mobile phone without any concern.

Tethered jailbreaking is a temporary process in which, after the reset of the mobile phone, it is unable to achieve the complete boot process without connecting the mobile phone with a computer with the help of a physical wire link. In the case of tethered jailbreaks, power-downs and stagnant batteries are common.

Untethered jailbreaking is a permanent and one-time solution to make an iPhone free from all the restrictions set by Apple. In this process, the mobile phone does not require any computer to facilitate the booting process.
