PS3 Themes » #1 Resource for PS3 Themes For those who don't already know about this site, it's pretty cool. I found it to be easiest to use the PS3 internet browser and download themes directly, but you can copy them to a memory stick from PC and then transfer to PS3 as well. All of these are free--just creative users sharing with others. Some of the dynamic themes are better than ones you can buy and you can find just about anything you are interested in. Also, there are several that I have downloaded just for the icons and then I use my own background picture.
that is definitely a great site to use for any theme you can find and i highly recommend to anyone looking for good themes not found in psn store
