On his blog Zibri has leaked a document about JerrySIM a special SIM that can patch the 4.6 bootloader using the STK exploit to enable firmware downgrade and custom firmwares.
Essentially this means an unlock solution for the 4.6 bootloader iPhones!
The document also outlines suggested release methods in order to "make JerrySIM available to the public at a minimal cost and avoid creating new scam opportunities for our *SIM chinese buddies."
According to a post on Zibri's blog he has made this document public due to his anger with the child like actions of some. He claims Acujo has been posting as Zibri in an effort to discredit his reputation.
ow.. ok.. enough with this childs. Here you have the document. It's dated a month ago...
Now, forget all this bullshits and try to have some fun in real life!
