I really need your help guys I am really new to iPhone Stuffs. I bought my iPhone and is already jailbroken and I don't like the stuffs that was in it so I decided to restore it to the original ROM and used iTunes, then I am getting error so I searched and found a solution in youtube : http://www.youtube.com/watch?v=lKkront2s_0 and solved it but now I get emergency calls only. I don't have any AT&T Sim or Phonebook Card sim cause I am here in the Philippines. Any solutions to this please? Thank you so much.
