Got a bit surprised by finding the jailbreak, that by definition:
process of removing the limitations imposed by Apple on devices running the iOS operating system through the use of hardware/software exploits...
See the Wikipedia article regarding jailbreaking
While a jargon expression, it is strictly associated with iOS devices. For Android devices, the jargon is "Rooting".
This terms exist and essentially mean the same thing, but each one is specific to a different device type using a different software. At Android Enthusiasts, we deal with only one type, Android, but yet we have three questions sitting on the main site since 2010 tagged jailbreak:
- Is it possible to completely brick your Android phone by using a Custom ROM?
- (how) can I install android on an iphone 4? [closed]
- What is the difference between jailbreaking and unlocking an Android? [closed]
Two of the three questions already have rooting
While two of the three questions are closed, one remains open and the tag remains active. Whether the questions are useful or not, that's another topic, what I'm discussing is:
Is it good to have a tag that's specificity directed to a non-android device? If not, should it be burninate and/or blacklisted, or by popular demand, merge and create a synonym?
