ultrasn0w updated to version 1.2.5 with more support for iOS 5.0.1

The latest version of ultrasn0w has just hit Cydia with support for unlocking additional devices under iOS 5.0.1. You'll need to have a compatible baseband in order for the unlock to work. Below is a list of compatible devices and basebands.

This version supports the following devices and basebands on iOS 5.0.1 -

  • iPhone 3GS - 04.26.08 - 05.11.07 - 05.12.01 - 05.13.04 - 06.15.00
  • iPhone 4 - 01.59.00

If you're planning on upgrading from an older firmware, make sure you preserve your baseband with a program like sn0wbreeze if you need an unlock. Then follow our guide on how to unlock your device via ultrasn0w on iOS 5.0.1. If you need more help, make sure you check out our jailbreak and unlock forums too.

i'm new to iphones, jailbreaking and find much of this a bit confusing since i've never actually done it before, with all the cydia's and snows and basebands blah blah blah talk.
For the layperson i'm reading this post to mean it there is still not yet a way to jailbreak a 4S. Is that a correct understanding?

I got a iPhone 3GS, baseband 6.15.00, on ios 5.0.1. I've tried using the ultrasn0w on cydia but it's not unlocking. I got a Vodafone sim (uk), anyone got any ideas?

do you have any idea when a updated version of ultrasn0w will be released? i have an iphone 4 with a baseband of 4.11.08 and i cant unlock it. i cut my sim to fit thinking that i did everything right and now i dont have a phone. thanks
