Ios 222 is dangereous and I wouldn't reccomend that either. What happens if you do it wrong?
Actually installing ios 222 is really simple. Less complicated and time consuming than installing homebrew channel. As long as you know enough english to understand the instructions, nothing can go wrong.
Well there you have it >_> If you don't know enough english don't use it >_>
<_< If you are using the other Ios DO NOT INSTALl 222!!! Period
