You can make a pandora's battery. There are also many versions that you can downgrade from without using a pandora's battery. I suggest just going to custom firmware, it has all the homebrew of 1.50 with all the new features of the newer versions. psp-hacks.com is the best site for all the stuff I talked about. Also about the internet and mp4 thing, yes you can do those things with the newer version, you don't have to do anything except for upgrade. But once again, I suggest upgrading to one of the custom firmwares at psp-hacks.com
