Hi, I recently finally managed to jailbreak my phone after following the instructions, using HJ split to get iPhone1,1_3.1_7C144_Custom_Restore. I restored using the custom firmware and now have Cydia.
However, my phone is not unlocked and it just says under Network: "Sim not provisioned" and No Service on it.
When it was doing the restore, I noticed it went to an "unlocking" phase using BootNeuter(?).
I connected it to the wireless network I'm currently using to go to this forum as we speak and I can use Cydia.
I don't know if this affects it but I did not put the simcard in while doing the custom restore.
