can somebody tell me what the big deal about unlocking-for-carriers is? Here in Asia (Thailand to be specific) we can use ANY carrier, ANY simcard with the iPhone 3Gs. Maybe we have a special IPSW that you guys back in the States don't have? Well hell... we do pay 4 times as much for this "already unlocked" iPhone anyways but yeah. Whatever it is, I wonder if it'll help the DevTeam put together a happy snappy tool for future jailbreaks?

Apple has allowed few countries to sell factory unlocked iPhones which allows user to choose any carrier. There is nothing special in your iPhone 3GS IPSW firmware file.

Does that mean it's all in the hardware then? Or is it factory-unlocked software? If it's hardware, then does that mean I don't ever have to worry about getting my phone 'locked' -- which means I can go ahead with the 3.1 update that the DevTeam released for the 3G iPhone (rumoured to jailbreak apps but not the "use-any-carrier functionality")?

If your iPhone is factory unlocked then you don't have to worry about carrier unlock. You can use PwnageTool 3.1 to jailbreak your iPhone 3G.
