Ultrasn0w 1.2.5 for iPhone 3GS & 4: iOS 5.0.1

For the iPhone unfaithful out there that likes to do the unlocking thing you might like to know that Ultrasn0w 1.2.5 is now available on Cydia, and word is this latest version now supports the latest OS from the Apple camp, iOS 5.0.1 and of course you will require a jailbroken device to make use of Ultrasn0w 1.2.5.

According to the guys over at iDwonload Blog, you’ll also require an unlockable baseband to utilise Ultrasn0w, but if you do have that then with Ultrasn0w 1.2.5 you should be able to unlock your iPhone 3GS or iPhone 4 running iOS 5.0.1.

To make use of Ultrasn0w 1.2.5 your iPhone 4 baseband needs to be 01.59.00 whilst with the iPhone 3GS you need bandbands 04.26.08 05.11.07 05.12.01 05.13.04 and 06.15.00

This new version of Ultrasn0w is only for the iPhone 3GS and iPhone 4 and does not bring any new baseband compatibility, and currently there is no support for the iPhone 4S, but apparently there are murmurs that Ultrasn0w could support the 4S at some point in the future.

So there you go, that’s your lot, if you won an iPhone 3GS or iPhone 4 running iOD 5.0.1and want to unlock it using Ultrasn0w 1.2.5 you can now do so, and if you do feel free to let us know how you get on and if all goes according to plan.

    I downloaded and installed the new ultrasn0w 1.2.5 for my iPhone 3GS (6.15.00), on iOS 5.0.1 and its still not “activating cellular network.” I live in Finland, and I don’t know if that should be the reason behind it.. I have also attempted to manually patch the older verson of ultrasn0w with no success, and I am completely out of ideas what to do. Anyways, I deleted the old Commcenterclassic file, I am not sure if that would cause the problem or if it was put back when i did a restore. But all I know is that I need help and I’m willing to do anything to get my Phone working again. Thanks.

    For  3GS 6.15.00 :
    You have to 
    1) flash ipad baseband with the latest redsn0w but uncheck install cydia.
    2) create a custom firmware with sn0wbreeze 
    3) Put in dfu mode and restore the iphone with the custom firmware
    4) Jailbreak iphone with redsn0w but uncheck ipad baseband and cydia

      V.P. did you have a problem with location services being on afterwards. That if on it disconnects your wireless and cellular services. I then comes back after a couple of seconds.
