I have tried to jailbreak and unlock a 3GS on 4.2.1 but it does not activate in itunes after installing the firmware.

I was able to boot tethered but i could get no network as the handset wasnt activated, nor any bluetooth or wifi.

I have tried installing the CF several times, but i am struggling to fix this.

Any suggestions?

I do not know what bootrom this is and i think it may have the ipad baseband
