I didnt wanted to ask about this, but i stil need to be sure besids my own eyes, if what is written here is positive(it wil work) or not :
"If the third field of your firmware version number: 5.8.7.0.1 is larger than 7 this jail break will not work on your device.
That means it will not work on: 5.8.8, 5.8.9, 5.8.10, ..., 5.8.99999999. (It's NOT possible at this time to downgrade and use this jailbreak)
Of course, this also means that it will not work on anything newer than the 5.8.x branch itself (i.e., 5.9.x, and whatever might come next

)."
Again, would appreciate very much your thougts in this decision,
