I just found these in the Classified section :-

APPLE iPHONE 3GS 16GB BRAND NEW OFFICIALLY UNLOCKED - 3,800 QR

APPLE IPHONE 32GB 3GS 3G S OFFICIALLY UNLOCKED BY APPLE - 4,250 QR

these are LEGALLY UNLOCKED WITH 12MONTHS WARRANTY
(the IMEI number is registered as being unlocked in the apple database), this means you can upgrade your firmware in the future!

its still cheaper a way lot cheaper

and ya now the price of iphone 3g 8gb is just 2000
