Wii System 4.0 update adds SDHC support for Photo Channel, new Wii Speak Channel update

“The Wii Shop Channel and Photo Channel 1.1 now support the use of the high-capacity SDHC memory card format” (the latter of this being the new part, photo channel)

“please note that an updated version of the Wii Speak Channel that supports the SDHC Memory Card format can be downloaded from the Wii Shop Channel. The current version of the Wii Speak Channel will not be able to communicate with the updated version, so all parties using the Wii Speak Channel will need to perform this update for continued operation”

Thanks to Weeman_com for the heads up!
