Does anyone know how to remove preinstalled apps?
Welcome to the forums, firefly.
Pre-installed applications (referred by many users as "bloatware") are best removed once the device is rooted. Some can be hidden or partially removed in a non-rooted device, but a clean removal via Root Explorer, etc is the best way to go.
Rooting the device, if you decide to do that, can be accomplished in more than one way. Have a long read in the Desire All Things Root sticky: http://androidforums.com/desire-all...oot-guide-updated-19-00-est-dec-4-2010-a.html.
