Lucifer_V has released Theme Swapper v0.2, an application that'll allow you to easily swap among different types of XMB themes, including changing the icons, backgrounds, battery bars, and other XMB accoutrements. According to Lucifer_V, you can also save your current theme to your memory stick and then flash it back at a later time.

Now, this is his first release, and we're actually quite impressed by what he's been able to do. Comments haven't been forthcoming on the forums post, so you may want to give the application a try and let him know what you think. Still, he has plans of expanding the app to flash whole themes in one go, so you may just be interested in seeing how this app pans out.

Just remember that this does have flashing capabilities and is therefore capable of possibly of bricking PSPs. Be very careful with using this app as it also doesn't have a manual, so you can avoid problems. That being said, enjoy the application.
