How would you like to change change your PSP's system version number, minus the flash? Well, JumpR's new homebrew application - Flashless Version Changer v2 - allows you to do precisely that in system information with the Slim version of Sony's handheld as well.

Before you do that, however, there are a couple of things that you should know, according to JumpR:

1. It doesn't allow you to play any new games or use any new features
2. This application is only compatible with firmware 3.90 M33, though JumpR may add other firmware versions later.
