    Hi. I have an iPhone 3GS 16Gb, bought it from someone. It has a 4.2.1 firmware and wasn't jailbroken when i got it so i did it myself. before jailbroking it did work with any sim card, so i did not need to unlock it. i would like to upgrade to version 4.3.3, and preserve my baseband, 05.15.04. As far as I know this baseband cannot be unlocked yet, so my question is, if i make a custom firmware, keep my current baseband, i am thinking of sn0wbreeze, will i be able to use it like now? with any sim card? or will i need to upgrade the baseband to 6.15.00 just to use it as a phone. i dont really know that much of iphones, so any help is appreciated, or a link or two. Thanks.

    Preserving the baseband is typically for basebands that can be unlocked. If you did what you're talking about you would still need to upgrade to the iPad 6.15 in order to unlock for other than AT&T (or whichever official carrier)

    Im confused. If i used this sim card before jailbreaking the phone and upgrading the firmware while preserving the baseband it should work right? As i said before the phone worked with any sim before jailbreaking it. Is there a way to find out if a phone is neverlocked? Btw i live in europe and using vodafone so i think the policies are different here.

    By any sim, you mean different carriers in your country? If that's so, then the iPhone could be factory unlocked.

    Well i tried 3 different carriers so it might be factory unlocked. Does that mean that it will always work with any baseband? No matter how new it is?

    Yes. Factory unlocked iPhones work no matter which iOS/Baseband combo it's on. So you can update it to 4.3.3 and be fine.
