No stylus... use ur finger play around   the interface was designed using finger touch like iphone.. u can see the key pad interface button is bigger than those using stylus phone.

not for most of the countries & not in the typical accessories, but some country like in india they gave additional stylus....need to buy it yourself if u comfortable using stylus..

advantage of using resistive touchscreen, u can use any object that produce electrical sensitivity (if i'm not mistaken this is the right term )..
capacitive only by heat sensitivity..

tips: touch by using tip of your nails give better response on resistive touchsreen..
