Region Free Dvd Players Good As Blu-ray Is The 40GB Ps3 Region Free?

Is the 40GB ps3 region free? - region free dvd players good as blu-ray

I bought a PS3 40 GB for a while and chat to the United States in the days and the price is because I am an inventory Games / Blu-ray DVD. But I know the weather games are region code free and climate of the Blu Ray is region free.
In addition, if not, you can use a trick, how to play with a DVD player for all regions.
