Sony has announced that the United States-specific upgrade to the PSP Firmware will become available August 12th.  The upgrade can either be directly installed using the PSP Network Update feature (which requires a 802.11b hotspot connection) or downloaded from http://us.playstation.com/psp and installed via USB.  Everything that was part of the Japanese release will be included in the American version, from the minor tweaks to the major features such as the web browser and photo sharing program.  Additionally, those early-adopters who couldn’t wait and have already installed the Japanese version can install the American version directly over the top of their previous upgrade, thus un-voiding the warranty on their PSP, which isn’t technically allowed to run “unauthorized software.”
