PSP Custom Firmware 3.90 M33 is out together with the 1.50 Kernel Add-on
Sony has just released a few days ago, the latest official firmware for the PSP. It’s 3.90 and I think it mostly benefits the PSP Slim users. Phat PSP users like me won’t really benefit anything from it. The new firmware has the Skype application now. Skype enables you to call using your computer to any phone around the world. Now you can call your friends from PSP to computer or PSP to PSP or PSP to phone via Skype. But you would need to buy the PSP mic and headset though. But that’s not great news. The great news is Dark Alex has done it again. You can go to his website now and download the new 3.90 M33 custom firmware and install it on your PSP.
But wait, there’s more! Dark Alex has also released the 1.50 Kernel for the 3.90 M33. You can grab it from his website too. If you have problems installing the latest custom firmware, do not worry because I will write a guide as soon as i have installed the latest update on my PSP.
I also heard that you can install 1.50 kernel on the slim now. Don’t get too excited because I’ll be writing a guide on that too.

@looneytunez2 and @em2x: If you are using custom firmware, change your region settings on the recovery mode to America. It’s only available on the Slim.
@rhythm07: I think you don’t need to but to be safe just revert your flash files back please.

@Shady: You should have plugged in your PSP to an AC Adapter. That’s what you get for bein too excited. Fix it with Pandora’s battery.
@Codename V: Yes it’s true.
