May 31, 2007 - Sony Computer Entertainment today released the version 3.5 firmware update for its PlayStation Portable. The update contains the following two additions:
Support has been added to allow remote play over the Internet in [Remote Play].
[RSS Channel Guide] has been added as a feature under [RSS Channel].
The big update here is the first one. While you were previously only able to stream content from a PlayStation 3 to a PSP via the Remote Play option while on a local network, the 3.5 firmware update in conjunction with the PlayStation 3's recent 1.8 update allows for streaming over the Internet.
Users can download the update via the PSP' Network Update option, or via this link via their computer if a WiFi connection is not available (note that the update wasn't yet posted on this site at the time of press).
