Yep, what frosty said, if you actually had clicked and installed to check them out then go into options/applications and delete.
However, the "link" icon will come back down again when you do a battery pull or resend your registration (which some OS do automatically with battery pull).
So, do as Frosty suggest, but one step further. Create a folder to put them all in then hide the folder.
To do this:
from home screen press menu/berry button (the one with the dots) to get to the app screen. Then press the menu/berry button again and choose, "add folder" type in a name that makes sense, IE: JUNK and then hit add.
Now go from each Icon/app you don't want/won't be using (sprint crud) and highlight hten hit berry button again and choose "Move to folder" find that folder and enter.
After you've moved everything then you can highlight the Junk folder and press berry menu and "hide"
If you need to see it again just go to the main app screen by pressing berry button on home page, press menu button again and hten "show all"
the folder will come back into view slightly faded showing you its a hidden folder.
