track the s-gold code, disasm and find the right pst of sim-check
Great guys. you are faster tham i.
I am not familiar with its mac os. but my idea is simple and should be direct.
The Sim lock would be dong by the S-gold in its flash. So read out the flash data should be the first step. And it's done by you.
The second step is, usually, in the .bin, it will read the info or IMSI + PLMN adn other info first, and then make a check
a. if it's a authorized sim card (belong to at&t), then
a.1 activate RF part, set value like agc, and get paging req
a.2 activate functions like wifi...--done by DVD
the flow chart of sim-lock, in most gsm solutions, are not very complex, and no en/decryption, no need to talk with switching center.
(that's the case that my s-gold can inplement sim-lock easily, hope it's the case for iPhone too).
here is my idea, may be helpful to our progress:
1. can the Jtag work on your iPhone hw?
2. you can read out the IMSI, PLMN from SIM already, track where the IMSI+PLMN is stored in RAM, and where in the bin process these data,
3. compare the cases of PLMN=at&t and PLMN = other(like Vdf)
the sim-check is done most in application layer, so it may not be executed very earlier, at least it shall be after the execution of ADC. etc.
4. activating wifi and 3rd app is done by AP, so it's far from the code of activating RF, and seems not so helpful as to my understanding
5. no arm11 knowledge is needed, just arm9 instruction is on
6. if you track the msgs btwn s-gold and the AP, it looks like in at-command,
can we agree on this? i need double check. logic analyser may need to store the msg.
7. i have once had the idea to use USB port to connenct a ULC modem, but dont know how to tackle its os and driver. mac is good, but not to me. maybe you can try.
8. arm-disassemble tool better have
the worst thing is, my iphone is out of my hand. G-dmd!
And if any 3rd party wants to get some hw info, i can help. but sorry not free.
i am closing to bankrupcy.
keep in touch!
what do you mean not free?

Guys dont misunderstand. no fee charged for my effort.
but if you wanna some .sch, or layout, there will be some fee charged by 3rd party.
they just split the pcb layer by layer and some labor work and check....
