If you have this mobile handset, could you describe the issues you having?
However, if you are looking to try out a Windows mobile device, Microsoft has a Windows Mobile 6 emulator which can be downloaded
from here, which simulates most of the features of a physical device.
The only drawback with the emulator is that it will not give an idea of what it is like using it for phone calls or what its battery life is like. However, it will let you try out windows mobile applications (using its virtual SD card) and go online, e.g. to test Pocket Outlook, mobile Internet Explorer and other Internet based applications.
