Hello all !
II can finally confirm about iPhone 1.1.3 unlocked ok at 8:30PM 15/01/2008 by our team and many help from GeoHot from US, Imth from VN, and some experts about iPhone from Hackint0sh forum ! Great thanks to those awesome guys.
This method is hardware method. So have to open phone.
Status now is:
- Unlock the iPhone with firmware 1.1.3 (baseband 4.03.13)
- Downgrade the phone to 1.1.2 then jailbreak it for normally using.
- Phone will work at: firmware 1.1.2 and baseband 4.03.13.
We are still researching on Unlock and keep the firmware 1.1.3 (mean jailbreak 1.1.3) ...
Will upload here some proof clip.
Thanks.
