So I finally got out of Sprint through a policy change argument. Now I have the iPhone 4S I paid full price for... AND THOUGHT WAS UNLOCKED.. And have an AT&T Sim Card in my wallet I just signed up for.. but problem is.. they don't work. (Ironically though she had tried another person's Sim card and she said it was connect to AT&Ts 3G stuff) The AT&T rep told me to call Apple and ask them to unlock my phone. But now I read that I have go through my carrier and ask them first THEN they'll ask Apple. Sigh. Damn it. One problem solved, another arises. Assistance/Advice anyone?
