    Just a quick question, I've been eagerly wanting to upgrade to the new firmware iOS 4.1 with my JB iPhone 3GS 4.0.1 , the only thing that is stopping from doing that is that I am unsure my carrier sim "Fido" which I assume its an official sim won't be able to work with my phone after if I update to this new firmware. Can somebody give me some advice on this.

    okay so preserving my baseband will allow me to use my Fido sim carrier in iOS 4.1?
