this iphone business has just been a long list of problems. does anyone have any guesses as to what else i can try? i have 3g, and have somehow ended up on 3.0 on 05.11.07. i cannot downgrade using fuzzyband as it tells me i have bootloader version 05.09. i cannot update/restore to 3.1 as i keep getting 1601, 13, 14, etc errors in itunes (many computers, many cables, different usb ports tried - nada). i have ultrasn0w, but of course it didnt unlock it properly, and i have no service. ah, complicated. any ideas? thanks guys :)

Download iTunes 9.0.2 first and update your iPhone with new FW 3.1.2 from iTunes then go ahead and use blackra and I believe you will be OK.

Those who have 3.0 and tried to update I had the exact same problem. No matter what restore file I used i got those generic Errors and the phone remained in DFU or REcovery mode with the itunes cable icon on screen. Same procedure with with my other iphone but the new one refused. The failure occurs when itunes does it check with the apple store then Apple says \"NOT\" The only possible way i found to bring phone back to life is just to the the restore right from itunes and let it restore you phone to factory with latest software. this will update your modem firmware which is most of what I wanted to avoid. Well once its all done and the phone is back to life use the black rain jail break and unlock tutorial and you will be back in business with unlocked phone. Just depending on your boot rom dont let the battery die.

same thing happened to me. This is what u have to check. 1. go to settings/General/Network/Cellular Data Network in the APN box u should have a url that is been provided by your provider. I guess when u Jailbreak and unlock it wipes it out

Did you successfully jailbreak your iphone? After the jailbreak, did you install the blacksn0w in Cydia?

For me too I got \"different sim detected\" error. Tried the jb and unlock process for 10-15 times . Finally used the process described in and it works.

i think the blacksnow will work with or without sim card. Did you try running the jailbreak and unlocking without sim?

Hi yes it will work without the sim, but never click the check online for the courier in itunes as it will block it and then you\'ll need the AT&T. hope this helped.

Hi, I have same question like following one still@firmware 3.0 wrote at 2009-11-10 19:03:59 I have a 3GS with version 3.0 still on it - but it is unlocked and jailbroken and has cydia installed. I did not upgrade to 3.1.2 because I am afraid of it becoming locked, or bricked. I try to install blackra1n through cydia, but after I click \"install\", I get this message: \"Note: the requested modifications cannot be applied due to required dependencies or conflicts that cannot be automatically found or fixed\"... and then it dos not let me install... I believe I need to upgrade to 3.1, but I\'m afraid that if I do that, I will have to reinstall Cydia or not be able to unlock it again....has this happened to anyone or does anybody know what I should do? I don\'t really get the certain answer. How do I upgrade to 3.1 before I use blackra1n tool to upgrade to 3.1.2. Because I\'m already jailbroken and unlocked with 3.0.1 version, should I use any tool to upgrade to 3.1 or just upgrade officially from itune?? Please HELP ME!! Much appreciate!!

Hi Justin, Re update your phone again, it should work with no problem, re do all the steps again, it seems there is something causing this reboot which will hopefully be solved after you reupdate it.

using bootloader has worked for a lot of people, but not for me. you might want to try it: let me know if you managed to get this to work, or if you find some other way. i\'m still in limbo. when i get some time i\'m going to try downloading the firmware and trying a different approach.

Hi, I have solved this problem by switching my sim with the AT&T sim card, and opened itunes, it asked me if i want to update the sim info i choose no, then i disconnect it installed my sim and connect again to itune, it asked me if i want to check online for the Currier i choose No and it is working again. thanks.
