From the [FAQ](https://superuser.com/faq) in the not about section:

> electronic devices, media players, cell phones or smart phones, except insofar as they interface with your computer

Your question was solely about a mobile device, not how it syncs with other devices. Also, please don't point to a 101 Windows Mobile tagged questions and then claim that they are acceptable. Some of those are closed, and most are surprisingly about how to solve a problem syncing a Windows Mobile device with a computer.
