[Q] Removing System Apps

view story

http://forum.xda-developers.com – I was wondering if there was a way for me to remove the apps that came preloaded but no functional uninstall button (twitter, facebook, amazon kindle, etc) without rooting it? I rooted my nook color successfully a few times last years, but I'd really rather not with the dell just because it really already has the functionality I was looking to get out of the nook (except these annoying apps). It seems to run low on space quickly, much faster than the nook. I don't even need the navigation apps as it is one that has the sim card blocked off so it's wi-fi only. If I do have to root it to get rid (HowTos)
