Unlock iOS 5 with UltraSn0w on iPhone 4S release day

The iPhone 4S will be alive and kicking down most doors tomorrow, people will be queuing for hours no doubt for their shiny new phone.

Tomorrow is also going to be big for all those that wish to unlock iPhone iOS 5, the reason we say this is because the new UltraSn0w unlock is releasing on the same day.

Thanks to iDB, they have reported that MuscleNerd confirms that the new iOS 5 compatibility update to the unlock tool, this will be releasing tomorrow after the planned MobileSubstrate update. MuscleNerd’s tweet said “Will coordinate ultrasn0w iOS5 compatibility update to come out *after* a planned MobileSubstrate update tomorrow”.

Please remember that the new UltraSn0w update will only work for 01.59.00, 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00 basebands, if you have a different baseband to the ones mentioned here then you will not be able to use this new updated tool, got to wait for the exploit.

If you would like to use the new UltraSn0w for iOS 5, please download / install iOS 5 if you have not already while preserving the baseband, you can do this by using RedSn0w. Once you are on iOS 5 with a preserved baseband, visit Cydia and then install UltraSn0w.

Please let us know if you will be doing the above, if you do this tomorrow please send in your personal opinions and of course let us know if you encounter any problems. Thanks

Whilst you wait for this release, how is your iOS 5 going anyway? Let us know what features you love the most.

    If you have a 3gs with the 6.15 bb you dont have to worry about it being updated,  go ahead and restore to stock firmware and then jailbreak using redsn0w, at least thats what i did and it worked fine, as of now i’m still waiting for the updated ultra snow to be released…..

    Ok so i have a 3GS that was unlocked and on 6.15.00 BB. Then i upgraded to 4.3.5 via iTunes and lost my unlock. Then i upgraded to iOS 5 and jailbroken with redsn0w. I’m outside the US so there is no chance i can get an AT&T SIM. How will i be able to unlock it if i can not pass the “SIM Validation screen” ??? How am i supposed to get into Cydia? Is there any other way to get the ultrasn0w????

    I have to report that ios 5 on 3gs(old bootrom) with baseband 6.15.00 and ultrasn0w crashes wifi and sim. It’s not stable yet. I hope for an update of ultrasn0w.
