Black packback/camera memory card/nokia phone/Hangout room keys - Singapore

We left a small black backpack (Quicksilver, Austin Keyte, Perth, West. Australia Ph: (08 93318887) grey and blue stripe) on a table outside the Singapore Zoo at 6.15pm on Tuesday 10 August 2010.  It contained a 1GB compact flash memory card, a black Nokia E71 phone with a mini SD card in a blue silicon case, 2 x The Hangout (Mt Emily) room cards plus a large light green glass ring and a large bead green bracelet.  Return of the memory card and SD card would be greatly appreciated.  Very upset 16 year old has lost his Singapore memories!!!  All phone and postage costs will be paid!!
