The 2010 MBP's use 1067 Mhz RAM, and the new 2011 models use 1333 Mhz RAM.
I currently have 8 GB of 1067 Mhz RAM in my 2010 MBP. I would like to know if the 1067 Mhz RAM can be run in the 2011 MBP and if the 1333 Mhz RAM can be run in the 2010 MBP so that I can keep my 8GB and put the 4GB 1333 in the 2010 model?

The faster RAM will probably run OK in the older machine, but the below-spec older RAM will slow the new machine down at best and may, under some circumstances, make it unstable or cause kernel panics. Don't use it. Buy RAM that meets the specifications for your machine.
