Hi, I bought an unopened iPhone on Ebay. It's wanting me to activate the phone under the ebay sellers number. I don't have the last four of their social security or billing zip code. I tried restoring the iPhone in iTunes and I also tried putting in my old SIM card but it always wants the seller to input their SS and billing zip code that matches their number. How can I get around this so that I don't have essentially a brick? Any help is much appreciated!
