Relax, you're golden. The original iPhone has been permanently pwned, and nothing Apple does can prevent your jailbreaking or unlocking your phone. If you have upgraded your phone, you will have lost your jailbreak and unlock, but you can easily get it back by running redsn0w 0.9.3. When it asks you to point it to the firmware currently installed on your iPhone, you will have to "trick" it by pointing it to the 3.1.2 ipsw instead. Redsn0w will jailbreak your phone and install BootNeuter, which you can use to unlock your phone.
