PSP Firmware 3.50 Released
As Sony promised, they have released version 3.50 of the PSP system software. With this update the PSP can now connect to the internet and the PlayStation Network using Remote Play on the PS3. Sony has also added an RSS channel guide to the PSP's internet features. The update should be available over network update at this point but
be aware that upgrading will spoil your chances of running homebrew any time in the near future. Consider yourself warned.
