the ones you can remove are Sprint Radio, Sprint TV, Blockbuster, 3D games, Qik...think there is one or two others.
...but I just noticed all those apps that can be removed are available via the market. they don't show as installed on the market just have the Update button. and will still only have the updte button after you uninstall. I also noticed in Sprint Zone under sprint apps, it still says Sprint Radio, and a few other i uninstalled are on my phone yet I uninstalled them via apps management. so are they truly deleted off your phone or not? just wondering.
