The 1.1.2 OOTB unlock is finally confirmed by geohot http://iphonejtag.blogspot.com/2008/...-unlocked.html
He did that by downgrading bootloader to 3.9 using a trick from old hardware method and then unlock using AnySim on the new downgraded bootloader . Secpack from 1.1.3 is also obtained which means we can expect a software unlock soon.
If i am not wrong we can use the 1.1.3 secpack to downgrade the 1.1.3 baseband firmware?
According to geohot those who upgraded to 1.1.3 have to wait for 1.1.4 , so how did TA_Mobile did it?? Ofcourse no one can question TA's authenticity, we are just curious to know the method..
