Mine worked ( took a while, so be patient ).
However while it accepts my SIM card now, it won't join the O2 network with my simplicity SIM in it
Any ideas if I've missed a step? (the SIM works in another phone)
i'm in the same situation as you, what i mean to say is, I've got a simplicity sim card too, i'm on 1.1.2 firmware ..
so, how can we be sure that this jailbreak would activate the phones for us ? since I never started a contract on this UK iPhone. I just jailbreaked it, which activated it, and i just put in a O2 simplicity pay monthly sim. and everything just worked.
any help is appreciated. cheers.
