I have read the forums for the most part and I have come to the conclusion that my problem hasn't been addressed yet so I would like to ask the members here for their assistance, please.

I have an iPhone which I downgraded to 1.1.1 then jailbroke (the whole *#307#, all the way to installer OkToPrep), then upgraded to 1.1.2 and then used the windows.bat to jailbreak.

Everything is fine. Except it isn't activated. I am using the stealthSIM and it worked before on my iPhone that I unlocked but I can't seem to do it for my aunt's phone. It says unapproved sim, or something of the sort. Am I missing something out, or am I doing something incorrectly?

Thank you.
