Hi where could i buy a USB cable to download pictures from a FujiFinepix F440 digital camera in Mumbai?

Fuji cameras work with the same USB cables used on Sony devices and TI graphing calculators with built-in USB. A PSP USB cable should do the trick

ebay.com

Mumbai is a big city, go to any mobile phone showroom or digital camera showroom, its easily available everywhere, but take your camera with you to check the compatibility of the connection to the camera

u can buy it from BIG BAZAAR, MOBILE STORE, or any branded digital camera store..............
if u r in no hurry to purchase it, u can go for ebay.com or amazon.com

it will be in all mobile shops
