I want to sell my 3G 8gb to raise money for iphone 4 (finally refurb upgrade on att).

Should I leave apps on it and keep it J/B to make more apealing to buyers? I am only worried about cydia account and the few cydia purchases i have. ANy harm in leaving cydia on? could buyer buy stuff in my name? Cydia does have log in so I guess I am safe. Any harm in leaving apps on? all free ones anyhow..
Phone is at 3.1.2, baseband(modem) at 05.11.07 (I figure this is atractive for unlockers)
shsh saved for 4.0, 4.0.1, 4.0.2, 4.1, 4.2.1

ANy recomendations? I want to get the most I can for it. Screen is good. A few dents on back corners from a few recent drops, and speaker is a little buggy (bad connection at dock assembly from recent rebiuld)...sooo
