Saurik, the creator of Cydia, recently voiced his opinion on the newly released TaiG iOS 8.1.1 jailbreak. If you’re worried whether TaiG is safe to use, then you shouldn’t worry much as MuscleNerd has already stated that it is pretty safe. However, if you’re not satisfied and want to know more, then Saurik is here to help. In a reply to a comment on Reddit, Saurik talks about whether he trusts the TaiG jailbreak and it is an interesting read.
According to Saurik, the TaiG jailbreak is probably safe to use. He isn’t sure about the safety because he is not someone who knows a lot about breaking apart a jailbreak tool and examining its working. He says that you should probably listen to MuscleNerd when it comes to these things.
He prefers the Pangu jailbreak over TaiG as the former uses an official Cydia Installation bootstrap and asked for Sauriks help in making the tool bug free. TaiG, on the other hand, isn’t very open about the person behind the jailbreak tool and their recent public announcement doesn’t reveal much either.
Of course, in all likelihood, everything is fine. Even though the identities behind TaiG are unclear, it is itself still an entity trying to build a brand, and has hopefully learned something from their previous miscalculations (which is likely why Cydia is included by default in this jailbreak: to help build back some community trust). MuscleNerd also hopefully knows what he is doing. I used the tool myself a few times this weekend, and other than “bootstrap is modified” (the extent to which I have yet to check) and “doesn’t include a package identifier for the untether” (meaning upgrading it will be confusing), I only got one failure that required me to restore (which at this stage in the firmware life cycle, and for a 1.0.1, is not to be unexpected). There are enough people using it to hopefully catch “phoning home” issues. So, the app is probably safe.
But, if you are really wanting to know “saurik’s opinion”, here it is: I am not the person who can answer the question of whether to trust this tool or not, and you might be better off asking people like MuscleNerd, who has apparently decided to sign off on it not doing anything malicious. That said, my squishier trust analysis leaves me a little wary: I’d love for TaiG to be more upfront about who did this work, to use official Cydia bootstraps, and to coordinate more with respect to bug reports. This reasoning is not, I realize, entirely “practical”, and I am known to sometimes make software judgements on painful moral grounds (such as the few years post-Cycorder where I refused to use ffmpeg, and seriously carried a DVD player around to peoples’ houses to avoid using software those developers had written; I also am somewhat “crippled” as I do not allow myself to use IDA, etc.). As I said: the app is probably safe.
Still, you shouldn’t face any safety issues when you jailbreak using the TaiG tool. If you want to jailbreak your iOS device and you’re on iOS 8.1.1, then you should jailbreak using the TaiG tool anyway.
