Tested on Ubuntu 6.10 and 7.04, as well as Fedora Core 6 and Centos 5, this key gave me hassle to transfer files with my phone (other devices are compatible but I have not tested).
It is also possible to use GPRS / EDGE / 3G support a phone to access the Internet through the wireless network.
The key also works on Windows (I did that can use Windows).
But I wanted to reassure Linux users: This key works perfectly, is cheap and requires no complex configuration for use (plug, it's ready).
