Please note that because I've had to resigned, market updates in the future will fail.
And if you already have chrome installed, you'll have to uninstall before updating to the patched version, as the signatures don't match.
Do not attempt to use this if the first Chrome beta doesn't work on your rom, or if you are not running an ICS based rom. This will not help you there.
