It’s quite rare for Research In Motion to offer service packs for Desktop Manager as normally they simply release a new updated version, but apparently that’s what RIM have done according to an article on Crackberry.
Word is the software is listed as Service Pack 1 (5.0.1) but doesn’t really hold much, a few minor bug fixes and not much else.
RIM Service pack 1 for Desktop Manager includes, user interface for using your BlackBerry as an IP modem, enhancements to the sync process for organiser data, support for Greek and Hebrew, and support for Windows 7, and support for new fields on the address book.
