Exactly which apps have you installed so far? There is one in particular which may possibly add a CWM folder (ROM MANAGER) even if you don't have Clockwork installed. Please do not attempt to download anything from ROM MANAGER if that's the case. The Prevail is not compatible and will be turned into a plastic brick by the ROMS on that app.
Clockworkmod is an add on system in which you can make a recovery backup of your phone if CWM is installed . To access CWM on a "stock modded" phone you have to boot into recovery by pressing the power button, volume up, and the camera button basically at the same time. Upon the reboot screen let go of the buttons.
