I installed the software on my laptop, which runs Vista. The paper instructions that came with the dongle didn't cover Vista, but putting the CD in gave me a menu, with one entry to read the Vista instructions, which I did.
I installed, discovered my phone, and it all "just worked". I'm now able to synchronise stuff with the phone, send SMS messages from the laptop, and use the phone as a modem to connect the laptop to the Internet. I can probably copy music and pictures on and off the phone too (but I haven't tried yet).
I clicked on the "Check for Updates" button on the CAMagic software, but the updates didn't work ("Failed to connect to Internet!!"). I went to the CAMagic web site and sent in a support request. They replied the same day saying there was a problem at their end, and again about 4 hours later to say they had fixed it - the update then worked, and the software upgraded itself - I now have two-way contact sync, apparently.
I'm happy with the hardware, and very impressed with CAMagic's software support.
