To all the hero users. We should put a list of what apps are needed when the phone is turned on and a list of apps that are ok to kill so that then phone can be functional. For example every time I have restarted my phone i see that sprint nav is there as well as the IM app. Do i really need these apps, is it ok to kill them without loosing the basic function of calling and receiving calls and texts. any help would do to all of us newbes.
