    What is your baseband?

    I'm guessing it's 05.14.02 which is currently unlockable. We are expecting a new unlock to be available any time.

    You should care about a jailbreak because you are going to have to jailbreak before you can unlock.

    If you are getting 1600 errors then it's probably because you are not in DFU mode properly (maybe you are in recovery mode? is the screen black)

    If you are on 05.14.02 then you should jailbreak the phone with limerain or greenpoison first. Then try to install fuzzyband through cydia. Fuzzyband is the only possible way of potentially downgrading your baseband to something unlockable. It ONLY works on 3G phones and only a limited number of them. Just try to run it and if it doesn't work then your waiting for the new unlock that all the other folks that are on 4.1.

    Thank you for the response. Downloading greenpois0n now.. I have a few questions real quick.

    I think I'm doing DFU correctly... screen is black.
    Yes my baseband is 05.14.02
    What is the host/address for fuzzyband?

    Fuzzyband can be found inside of Cydia through a search. When you launch it, it will seem like it is stuck on "Querying Modem", but just give it a minute or so to finish. It will then tell you if you can or cannot downgrade/upgrade your modem's baseband. It would have to be one of the very first models of the 3G for it to work.

    If your baseband is 05.14.xx , you cannot unlock unless you have bootloader 5.8, use iforecast to see if you have it. You can jailbreak your 4.1 with Redsn0w 0.9.6b2

    Ok, I can't find a download on iForecast for Mac.. So since I need this phone for work, ASAP what is the latest firmware I can unlock/jailbreak? And now I have to downgrade my firmware, which I have a feeling is going to be a pain in the ***... Whatever happened to the one click ziphone days lol

    You can check with iH8sn0w.com | Jailbreak your iPod touches and iPhones and download iforecast to see if your bootloader is 5.8.

    You arent going to be able to unlock with that baseband unless you have one of the very few 5.8 bootloader iPhone 3G. Downgrade to 3.1.3, use redsn0w 0.9.4 to jailbreak then install fuzzyband from cydia to check. But it is a long shot.

    If you have 05.14.02 then you cannot unlock your phone. The only way to downgrade a baseband is if you have the rare iphone 3G that has bootloader 5.8. Since you went to 4.1 you should now jailbreak with Greenpoison and then using Wifi look for Fuzzyband in Cydia. If fuzzyband tells you that your phone modem cannot be downgraded then you have to wait for the dev team to release the unlock once Apple drops 4.2.

    I am not sure if f0recast has been updated for Mac but it still may work just for the purpose of showing his bootloader. ih8snow.com is down right now though.

    Greenpoison doesnt work on iPhone 3G. But maybe your idea is less time consuming than mine. If you are at 4.1 right now just use redsn0w 0.9.6b2 to jailbreak and then check fuzzyband.

    My apologies, I have been out of the iphone loop for a minute. With already being on 4.1, what would be the easiest/fastest way to unlock my iphone? (3G)

    as of now you can't, you are stuck waiting for the next unlock, that is unless as mentioned before you have the 5.8 bootloader (would have to be very early 3G to have it), you can restore to 3.1.3 and install fuzzyband and it will tell which bootloader you have

    because when you updated to 4.1 your baseband was updated and that particular baseband can not be unlocked at this time

    Thank you for the correction. I meant to type Limera1n, but have the greenpois0n stuck in my mind.

    I am sorta using it. I use OSX in VMWare to create the custom firmwares, but I use Windows to install them. I have all of the components now to have OSX on one hard drive and Windows on another hard drive. I just have to actually put the second hard drive into my laptop and do the installs.

    I used iReb to get passed the 1600 error yesterday.
