    Default New idea for iPhone unlock based on iBoot

    As we know,baseband firmware is protected by 1024-bit RSA,and we know MD5,SHA-1 also been crack .

    if Apple not singed the whole firmware by RSA, just signed the MD5(firmware),we can use mad5coll.c to make MD5(oldfirmware)==MD5(newfirmware), and donot change RSA signed. the iBoot will load our newfirmware to baseband chip. it's open the door to true unlock the iphone.

    So its SHA-1, good, but how can we find out if Apple signed the whole firmware?

    i do some research .SHA-1 is more difficulty, some paper show that new algorithm can reduce from 2^80 operates to 2^69 opeartes,but too long in real world ,may be thousands of year.
