A frictional pad in combination with a handheld electronic device upon which the frictional pad is adhered and an upward facing support surface upon which the handheld electronic device is selectively disposed and held in a non-adhesive, non-slip fashion by the frictional pad. The frictional pad includes a polyurethane dome adhered to the handheld electronic device by the adhesive film. The dome has a broad, flat shape with an outfacing surface facing the upward facing support surface with a flat and smooth center parallel with the adhesive film and surrounded by a radius perimeter. The outfacing surface of the dome contacts the upward facing support surface and is tacky to releasably hold the handheld electronic device to the upward facing support surface.

1. A frictional pad in combination with a handheld electronic device upon which the frictional pad is adhered and an upward facing support surface upon which the handheld electronic device is selectively disposed and held in a non-adhesive, non-slip fashion by the frictional pad, the frictional pad
1. A frictional pad in combination with a handheld electronic device upon which the frictional pad is adhered and an upward facing support surface upon which the handheld electronic device is selectively disposed and held in a non-adhesive, non-slip fashion by the frictional pad, the frictional pad comprising: a) an adhesive film adhered to a surface of the handheld electronic device;b) a polyurethane dome affixed to the adhesive film and adhered to the handheld electronic device by the adhesive film;c) the dome having a broad, flat shape with an outfacing surface facing the upward facing support surface with a flat and smooth center parallel with the adhesive film and surrounded by a radius perimeter;d) the outfacing surface of the dome contacting the upward facing support surface and being tacky to releasably hold the handheld electronic device to the upward facing support surface; ande) the polyurethane dome being formed by a polyol and a catalyst in a ratio of between 0.63 and 0.85. 2. The combination in accordance with claim 1, wherein the dome has a hardness between 10 and 35 Shore D. 3. The combination in accordance with claim 1, wherein the outfacing surface of the dome has a coefficient of friction of between 0.3 and 0.1 in accordance with ASTM D 1894. 4. The combination in accordance with claim 1, wherein the dome is translucent or transparent; and further comprising a graphic layer disposed between the adhesive film and the dome and visible through the dome. 5. The combination in accordance with claim 4, further comprising: a film with the adhesive film on one side; andthe graphic layer printed on the other side. 6. The combination in accordance with claim 4, wherein the graphic layer further comprises an etched metallic layer. 7. The combination in accordance with claim 4, further comprising: a substrate with the adhesive film on one side and the graphic layer printed on the other side; andthe substrate is at least translucent so that the entire pad except for the graphic layer is translucent or transparent, and the support surface is visible therethrough. 8. The combination in accordance with claim 4, wherein the graphic layer includes a hologram. 9. The combination in accordance with claim 4, wherein the graphic layer includes a mirror surface. 10. The combination in accordance with claim 1, wherein the dome is translucent or transparent, and further comprising: an LED and a battery power source embedded within the polyurethane dome. 11. The combination in accordance with claim 1, further comprising: an inclusion embedded within the polyurethane dome, the inclusion including a gem. 12. The combination in accordance with claim 1, wherein the pad has a thickness between the outfacing surface and the adhesive film of between 1-2 mm. 13. The combination in accordance with claim 1, wherein the polyurethane dome includes a scented material permeable through a polyurethane material of the dome. 14. The combination in accordance with claim 1, wherein the pad forms a rigid, self-supporting layer. 15. The combination in accordance with claim 1, wherein all of the outfacing surface of the pad between the radius perimeter is flat and smooth and continuous. 16. The combination in accordance with claim 1, wherein a strength of an adhesive bond between the adhesive film of the pad and the handheld electronic device is greater than a tacky cling between the outfacing surface of the pad and the upward facing support surface. 17. The combination in accordance with claim 1, wherein a contact surface between the adhesive layer of the pad and the handheld electronic device is greater than the outfacing surface of the pad contacting the upward facing support surface. 18. The combination in accordance with claim 1, wherein a contact surface between the adhesive layer of the pad has a perimeter greater than and circumscribing a perimeter of the outfacing surface of the pad contacting the upward facing support surface. 19. A method for using the combination in accordance with claim 1, comprising: selectively placing the handheld electronic device on the upward facing support surface with the outfacing surface contacting the upward facing support surface; andselectively placing the handheld electronic device with the frictional pad thereon into a pocket of clothing or a clothing accessory. 20. A frictional pad in combination with a handheld electronic device upon which the frictional pad is adhered and an upward facing support surface upon which the handheld electronic device is selectively disposed and held in a non-adhesive, non-slip fashion by the frictional pad, the frictional pad comprising: a) an adhesive film adhered to a surface of the handheld electronic device;b) a polyurethane dome adhered to the handheld electronic device by the adhesive film;c) the dome having a broad, flat shape with an outfacing surface facing the upward facing support surface with a smooth and flat center parallel with the adhesive film and surrounded by a radius perimeter;d) the outfacing surface contacting the upward facing support surface and being tacky to releasably hold the handheld electronic device to the upward facing support surface;e) the polyurethane dome includes a polyurethane material being formed by a polyol and a catalyst in a ratio of 0.63 to 0.85;f) the dome being translucent or transparent;g) a graphic layer disposed between the adhesive film and the dome and visible through the dome;h) the outfacing surface of the dome having a coefficient of friction of between 0.3 and 0.1 in accordance with ASTM D 1894;i) the dome having a hardness between 12 and 21 Shore D; andj) the pad has a thickness between the outfacing surface and the adhesive film of between 1-2 mm. 21. The combination in accordance with claim 20, further comprising: a film with the adhesive film on one side and the graphic layer printed on the other side. 22. The combination in accordance with claim 20, wherein the graphic layer further comprises an etched metallic layer. 23. The combination in accordance with claim 20, further comprising: a substrate with the adhesive film on one side and the graphic layer printed on the other side; andthe substrate is translucent or transparent so that the entire pad except for the graphic layer is at least translucent and the support surface is visible therethrough. 24. A frictional pad in combination with a handheld electronic device upon which the frictional pad is adhered and an upward facing support surface upon which the handheld electronic device is selectively disposed and held in a non-adhesive, non-slip fashion by the frictional pad, the frictional pad comprising: a) an adhesive film adhered to a surface of the handheld electronic device;b) a polyurethane dome affixed to the adhesive film and adhered to the handheld electronic device by the adhesive film;c) the dome having a broad, flat shape with an outfacing surface facing the upward facing support surface with a flat and smooth center parallel with the adhesive film and surrounded by a radius perimeter;d) the outfacing surface of the dome contacting the upward facing support surface and being tacky to releasably hold the handheld electronic device to the upward facing support surface;e) the outfacing surface of the dome having a coefficient of friction of between 0.3 and 0.1 in accordance with ASTM D 1894; andf) the dome having a hardness between 12 and 21 Shore D. 25.
