I need to unlock/jailbreak my iphone A2103 (2G original iphone)?

I recently forget my i phone passcode and restore my phone using itunes but now it not accepting my Vodafone sim and when i try to restore my device it is giving me error "We're sorry, we're unable to continue with your activation at this time. Please try again later, or contact customer care."

I tried to unlock it by searching online but no success. Please provide a quick fix of this issue. Appreciate you quick reply.

Hi you can reset your phone again

  • Would you choose original iPhone 5 or new iPhone 5c? I want to get a new phone and I'm thinking if the iPhone 5 and the iPhone 5c are going to cost the same amount of money, which one would I choose? Considering the 5c is plastic. What would you choose?
  • Will I be able to unlock my iPhone if I don't know the original carrier? Recently my old iPhone broke (water damage) in which my mother gave me her new but un used iPhone 5, I know it's locked to a different network. But I don't know which network, if I went to a shop to get it unlocked, would they be able to if I didn't know the original sim carrier?
  • When you load an mp3 to iTunes, do you still need the original file? I download my music through other music downloading sites/stores and I only use iTunes to organize them and get the music to my iPhone. When I download these mp3's they are stored in my iMac's Downloads folder and I have a ton of music in that file. Do I still need these mp3's or can I delete the ones just floating around in my Downloads folder?
  • Iphone 4s 5.1.1 activate without original SIM? I have a friend and he is from France( I'm from Greece)! He just gave me an iphone 4S because he bought a new one!
