I saw this tip on changing the device Name on Windows Mobile 6 device over at Jason Langridge' web site and I thought I'd pass it along as an FYI. He had a customer ask how they could change the device names of Windows Mobile 6 devices to align with their PC/Laptop naming conventions. So he provided the following tip:

On a Windows Mobile 6 Professional device you can change the device name in Start..Settings..About and then select the Device ID Tab.

On a WM6 Standard (Smartphone device) using Vista you can name a device on the 1st pairing to the Windows Mobile Device Center (WMDC). You cannot rename it afterwards from WMDC, but you can do this in Explorer if it is paired to WMDC. Just browse to My Computer, right click on the device (or select and press Enter) select properties and you can rename; if you disconnect and then reconnect the new name is reflected in WMDC as well. There does not seem to be a way to do this on the phone itself, but if I remember correctly you could never do this on SmartPhone, only on PocketPC…
