Whatsapp was only available for Nokia Single Sim mobiles till now.But Whatsapp has recently given support for Nokia Asha 305 and other dual sim mobiles. You can install Whatsapp from the nokia store or you can download the files from the link provided.Enjoy......
NOTE : Copy the files to your memory card using external card reader . When you copy the files using usb the jar file doesn't get copied ( I had this problem). And run the jar file... If u run the jad file you will get invalid application error.
