Hi all, Okay, I have tried to do as much research as possible into the issue of unlocking the 3G iphone. Mine has been jailbroken using the pwnage tool on Mac. I am on 2.2 firmware but the baseband firmware is 02.11.07. I have a custom logo on boot up (my company logo) and all of my settings set. I have seen instructions for yellowsn0w that say you can install it and have it work on that firmware. I have seen other instructions that say you need 02.28.00 and it will only work with that firmware. 1. Which one is accurate? 2. If I have to upgrade, is there a way to upgrade just the firmware without having to re pwnage? I saw a link that describes this but the download seems disabled. Can anyone verify whether this is legitimate or not? - http://appearth.wordpress.com/2009/...g-actualizar-baseband-a-022800-sin-restaurar/ 3. If not, is there a way to re-jailbreak without using quickpwn so that I can put my custom boot logo back on there, and still have the upgraded baseband firmware? 4. Is there a way to back up all my installed apps (non-app store) without have to re-install each one individually? I have done searches for this information but that is how I have come up with the conflicting information, hence my creation of this thread. Thank you for any and all clarification on this conflicting information and the appropriate methodologies.
