happy to read you have a working iphone to compare.
so before you give it away please try to do the following,it may help us in the future.
If we still belive it is a software iusse and this is in the Nor,like orcinus said, we can proceed if you agree in this way.
Thanks to the dev team we can extract from the phone all the NOR content with NORDumper.
I have already done on my iphone,i have it on my desktop.
So proceed this way for both the working and non working iphone,same firmware 1.1.1,Bl 3.9,ssh bla bla bla...
download NORDdumper from here http://iphone.unlock.no/files/NORDumper and copy it to /usr/bin/
download Putty from here http://the.earth.li/~sgtatham/PuTTY/.../x86/PuTTY.exe and connect to iphone
run the following command
chmod +x NORDumper
launchctl unload -w /System/Library/LaunchDaemons/com.apple.CommCenter.plist
NORDumper nordump.bin (Wait 10/20 minuts and is done,copy from phone to pc)
launchctl load -w /System/Library/LaunchDaemons/com.apple.CommCenter.plist
N.B. before launching NORDumper "airplane mode" and autolock to "never" (if you don't want to say fack.... to who stopped the process calling you just in the meanwhile, like i did).
Once done the process now we need to compare the two Image of the NOR.
This is very hard to do but right now we can try to do it hoping some guru can help as in the future.
obviously i'm not asking you to give me the file i know there is the imei in it,you have to try yourself.
Right now we can compare the file in an HeX editor or disassemble it like i did with mine using IDA PRO Disassembler(very nice this one you can compare the single strings and whatch if they are similar or broken).
we have to try to find the iusse and then go on patching it with the good one.
than we can reflash just the part of the nor.(for this we need help and we are going to ask for this only if we have really found
If you think all this is stupid and have a better way i'm ready to try!
Finally: please make olso a backup of all the file in the working Iphone to desktop so that if we need it we Have it.
