Apple Activating iPhone 2G

[Krestent]

So my iPhone 2G was unlocked, and then it refused to boot, so I had to restore it. Now it's not activated, and it's still recognizing my T-Mobile SIM. What's the best way to activate this thing?

You could use redsn0w 0.9.4 to hacktivate, jailbreak, and unlock iOS 3.1.3. When redsn0w asks for an IPSW, point it to iOS 3.1.2.
