HP Has released a minor software update for its h2200 and h1900 lines of Windows Mobile-powered iPAQ handhelds improving their Bluetooth capabilities. The 1.1 MB patch adds support for Combination Key pairing with other Bluetooth devices, which is required by a small number of Bluetooth handsets - such as the Nokia 6820 - to enable pairing and carry out subsequent communications. The patch is available as a free download from the HP support web site.
