1 Apple Says Don’t
Probably one of the biggest (and most compelling) reasons not to jailbreak your iPhone or iPad is this: Apple says don’t. Apple stated that modifying iOS and attempting to use unauthorized apps could cause security vulnerabilities, instability, and shortened battery life. Plus, jailbreaking could even affect Apple services like iCloud, iMessage, and FaceTime.
Additionally, it seems like jailbreaking an iPhone is falling out of favor. Sure, in the earlier days of iOS you were able to take advantage of many features and tools that Apple had not yet integrated. But as Apple has improved their iOS, added new features, and patched holes, jailbreaking seems to be losing steam. “It used to be that you got killer features that almost were the reason you owned the phone,” Cydia creator Jay Freeman shared with Motherboard. “Now you get a small minor modification.”
