IMO, I don't understand all the negative stuff about evasi0n7.
1. First of all, it jailbreaks your iOS device (No one is forcing you to jailbreak).
2. Installs Cydia (as per usual) and TaiG (if your system is in Chinese).
3. Most JB related stuff on Cydia doesn't work (because devs havent tested their apps yet, which is to be expected).
So what's all the fuss about? I know TaiG came with preinstalled repos of cracked apps, but hey, Cydia is full of those cracked repos as well. People who likes cracked apps already knows how to get them (preinstalled or not).
It seems that some people are affected by the fact that evad3rs were paid to install TaiG. But who the **** cares? They spent so many hours developing this jailbreak, they got their money, you get your free jailbreak, so ****! All those ******** rumors about data being sent to China is all full of **** as well.
Personally, I haven't jailbroken my iPhone 5s yet as I'm waiting for some stable tweaks, but it's getting really annoying with all those jailbreaking ******** crap that some people are whinning about. I wonder whether some of those whiny bitches are some noobs who just got their iOS devices this year and haven't followed the jailbreaking scene from the very beginning.
BTW, if you really don't like it, again **** and use your stock iOS or go Android.
