This one worked for me.

You have to install ultrasn0w using iExplorer or DiskAid.

NB. you will need Itune v10 or later and Quicktime installed and run atleast once to use iExplorer.

Put the ultrasn0w.deb in var/root/Media/Cydia/AutoInstall

If the Cydia/AutoInstall directory is not there, then you create one by rightclicking/add directory then rename it to autoinstall.

Lastly, reboot your device.

Note: ultrasn0w has a dependency on Mobile Substrate, so if this is not installed on your device (if this is a fresh jailbreak it will not) then you need to download Mobile Substrate and Substrate Safe Mode and install them the same way explained for ultrasn0w. This should be done before installing ultrasn0w itself.

Good luck!!

Note that you will also want to unhacktivate your device as soon as possible. You can either do this by "deactivating" in redsn0w and then reactivating using the original carrier sim whilst connecting to iTunes, or if you are feeling particularly tech savy and the original sim is not available, you can also try using SAM to obtain correct activation certs for your phone. If you do not correctly activate the phone, push notifications will not work, and you will experience excessive battery and data drain whilst your iPhone continues to "hunt" for the correct certs.

There's also a basic guide to SAM in the FAQ, although @JuergenWest may have a better answer.
