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.

i have tried this on so many iphones and its not working once i put tmobile sim card it tells me to plug it into itunes because it detected a different sim card :S i’m so confused on what to do
Could you please tell me the details of your iPhone and iOS version?
Thanks a lot. had lost all hopes after reading stuffs in google … all app says if you have bootloader 5.9 then you won’t be able to unlock.
But rather than adding the repository in source, an easier way is to search for ultrasnow app in search and install it.
Thanks,
Arun
