Sony, in their ongoing quest to keep people up to date, have released a new firmware update for the PSP while a new PS3 update is on the way. The latest PSP firmware is 3.70 and adds quite a bit of functionality. Most notable is the addition of themes, in case you find the XMB becoming a little boring. The new included theme is “Cookies”, with all icons being shaped out of various cookies. It sounds ridiculous, but it actually looks sharp. Future themes will be released on various websites, but primarily the official PSP site.
Other feature-additions include the ability to listen to music while browsing photos or a slideshow and also a scene search for movies. The PS3 will be launching firmware 1.93 later this week which will simply patch up a few problems that were unveiled with 1.92.
Taking into account customer feedback and some internal testing, we will be making available in the next few days a firmware update for the PS3 (1.93) that fixes the network disconnect issue that some of you have experienced as a result of downloading Firmware 1.92. In addition, we are adding a new firmware update for PSP (3.71) as well, which adds many features that readers of this blog have requested.
