A misprint in the CD User Guide for the HP iPAQ hw6500 mistakenly indicated that the software bundle includes the HP Protect Tools security software. The reference has been removed from the Mobile Messenger CD but HP has also decided to offer the HP Protect Tools security software for free for hw6500 users.
Before you can download the software, you will need to supply your serial number. As well, the software will not operate correctly on any other HP iPAQ models.
Nicely done, HP!
