Hi this is latest version iphoneyeta 4B.
it includes Chicken baseband,barrel and semitether.
For all didn’t know what is chicken baseband?
You can update baseband without internet connection using redsn0w.
just wait for some features that jailbroken quick tool had.
Sorry for some delaying features…
not tested in windows 7 please report some bugs..
