    i have an unlocked iphone 4 on version 4.2.1 .. modern firmware 01.59.00

    the phone needs to still be able to be unlocked or else i can't use it. it is currently unlocked through Ultrasn0w.

    Thanks for any help you guys might have...

    You can update to 5.0 and preserve your baseband with a custom firmware but it is a tethered jailbreak right now so you may want to stay put until a untethered jailbreak is out.

    Thanks. I'll wait for untethered

    so.... 3 months later, is it possible for me to upgrade to IOS 5 and keep my iphone 4 unlocked?
    is there an untethered jailbreak yet and will it make me lose the ability to use ultrasn0w for a simple unlock?

    thanks

    Yes, snowbreeze, redsnow or pwnage tool (latest version) can all make custom 5.0.1 firmwares that can preserve your baseband. Then install ultrasnow to unlock after.

    I guess you don't need help then. I was simply asking which one you want to use and I WAS going to find a tutorial for you. Oh well, good luck with that.

    Follow the guide i posted. Use redsn0w to create a custom IPSW, put phone into Pwned DFU mode using redsn0w, and restore your phone in itunes using the NO_BB IPSW.

    When its finished restoring. Reuse Redsn0w and jailbreak the device. After open up Cydia and install ultrasn0w.

    Thanks

    I am in the same situation, iPhone 4 with 1.59 on T-Mobile. Do I need an AT&T sim handy to activate the phone at any point (using that redsn0w guide) or no?
