Rooting Android 3.0

[jamesl22]

Hi,

I have purchased a "Cambridge Sciences G7-III" running Android 3.0. I have tried SuperOneClick and z4root but I believe these are for Android 2.*. How can I root my device? I need to fool android market that my device is a Samsung Nexus S so I can unblock all the unsupported apps. I'm sick of downloading the apks.

Thanks,

James
