I too would like to update 2.6 to 3.0 using the binary. My system runs on a hard drive using berryboot. In a comment above, it was stated that if you updated using the binary you would not get all the effects of the upgrade and the rom files would not be cleaned up.

So my question:
1) what do I need to do to manually clean up my rom files after I upgrade.
2) what do I need to manually change to get the full effect of the upgrade.

Thanks
