Now here's something very interesting. Firmware 2.71 has been officially released on Sonys websites!
You can check out the video here. (via PSP3D forums)
You can download it here from Sony.
Unfortunately my own server is down at the moment so you'll have to download it from the original location.
FEATURES:
--Game demos can now be downloaded from the internet and saved to the Memory Stick duo
--Video output can now be displayed correctly when external tuner is selected in Location Freeplayer.
Enjoy!
Edit: This update is available via network update.
