can't sync 2g 3.1.3 after unlock, Lockdown file update
I have an old iPhone 2g running 3.1.3. I jailbroke it with Spirit, installed Bootneuter, flashed it, and Bootneuter reports that it is unlocked.
When I try a different SIM in the device, I get the "Different SIM detected" message.
So I tried updating the files in /private/var/root/Library/Lockdown with the hacked ones. With the new files in place, the phone won't sync to iTunes, it reports "unknown error" 0xE8000001.
If I restore the old lockdown files, it syncs fine.
I have seen some posts that say I need to jailbreak it using redsn0w with a non-ATT SIM inside. But I'd like to have the option of putting in a local SIM when traveling. Would I need to jailbreak it for every new SIM?
