3GS jailbroken upgrade

[AndyTKD]

I have a 3GS with old bootrom, currently jailbroken with 4.0 and modem 05.11.07.

It was jailbroken with Pwnagetool

Cydia says SHSH : IOS 3.1.3,4.0,4.0.1,4.0.2

how can i upgrade to IOS4.1

I have access to a Mac and Windows (preference is mac)

thanks

If you want to use a mac then you'll need a link to download some snowbreeze 2.0.2 created custom firmware for 4.1. Shouldn't be hard to find.

If you've got access to a PC then download snowbreeze and make one yourself.

Then simply control button (is that the correct name?) and restore like you did with the firmware to get you to 4.0.
