Hi Sandeep you need not downgrade any more. Thanks to GeoHot’s new unlock tool called Blacksn0w you can now unlock even if you are on 05.11.07 baseband.

You can use this tutorial to unlock your 05.11.07 iPhone.

thanks guys… the baseband has been updated to 05.11.07 and not able to downgrade it as the bootloader is of 05.09 version. waiting for the solution. Do keep us posted on that. :-)

@John Yeah I totally understand how annoying it is. I am afraid a jailbreak solution for 05.11.07 baseband is not currently on the Priority list of the iPhone Dev Team..

Hopefully a new solution presents itself soon. Many are counting on GeoHot to release a new tool.

Will keep you updated.

We’re all waiting on the 05.11.07 unlock solution. I also recently bought a new 3GS phone and it came with the 3.1 os and the 05.11.07 baseband. I’ve JB’d the phone using pwnage 3.1.4, but the unlock won’t work. I bought the phone in the States, but live in China so need the phone unlocked so to use it with my local service provider. Right now I’ve got a very nice iPod Touch with a camera!

@Uri Goldberg That’s not possible I am afraid. If you are on an iPhone 3G purchased during the first two months of release then u can downgrade to 04.26.08 using the tutorial below

However, if u are on any other model there is no tool available to downgrade. I will give u an update if any solution is out.

Hi Rohit,

Is there a way to go back to the 04.26.08 modem firmware from the 05.11.07? I jailbroke using Pwnage Tool 3.1.4 and installed the iPhone1,2_3.1.2_7D11_Custom_Restore.ipsw, thinking that this restore step will remove the 05.11.07 and replace it with the previous one but that didn’t (couldn’t?) happen. Any suggestions would be appreciated.
