I am trying to activate my iPhone 3GS, but while doing so it says...”Your iPhone could not be activating because the activation server is temporarily unavailable Try connecting your iPhone to iTunes to activate it, or try again in a couple of minutes. If this problem persists, contact Apple Support at apple.com/support". I also tried to connect with iTune. But it again says.."We're sorry, we are unable to continue with your activation at this time. Please try again later, or contact customer care". I had repeat this process for several time but no progress at all. Can you help me please?
Call AppleCare and give them the model and serial number of your iPhone and ask which cell carrier it is locked to. Then contact that cell carrier and see what their unlock policy is and if you qualify.
