How to remove pre-installed apps like Peep and Friend Stream from my HTC phone?
You can only fully uninstall pre-installed applications by using ADB. You need to find out what the package name is for the specific app, and enter this in the ADB prompt:

adb uninstall &lt;package.name&gt;


For example, to remove the Maps application:

adb uninstall com.google.android.apps.maps


So far I haven't found an easy way to figure out the package name for an app though.
