"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.
The main feature we've added with the recent updates for PSP is the ability to set themes on your PSP. Over time we will be providing themes on PlayStation.com, our official PSP site and through PLAYSTATION Store. You can download themes based on some of our popular titles."
