Does iPAQ Pocket PC h1930 and h1940 series support SDIO?
Yes, Both models support SDI/O (Secured Digital Input/Output). Use of SDIO (Secured Digital Input / Output) will require installation of driver software for the h1930 and h1940 models and SDIO cards. HP is supporting SDIO Now! as a standard way to ensure SDIO cards will work across Pocket PC devices. Once SDIO Now! drivers are available for SDIO cards we will work with the SDIO card manufactures to ensure compatibility and make the necessary h1930 and h1940 software upgrades available. See the iPAQ Pocket PC website for latest list of tested SD cards.
