iPhone and iPad owners may use the "JB" to abbreviate "jailbreak." JBing a device removes the device's default system restrictions. For example, on a JB'd iPhone, you can install apps from outside Apple's App Store and modify the phone's operating system.
Many third-party apps and tools allow iOS device users to JB their devices. However, JBing a device violates Apple's end-user license agreement, so you should think carefully before using a JB tool.
Other uses of JB
Android users may use JB to refer to Jelly Bean, a previous version of the Android operating system. Additionally, non-techies may use JB to refer to someone they consider jailbait.
