Sorry for the above, made a mistake. The phone i had was the Samsung SGH-T809 and not the D900.
As for the SDA its a smartphone. Here is the link to the review.

I love this phone, its a bit on the bulky side but it has wifi and bluetooth. You can also use it as a modem on your laptop. It has tons of features… superb battery life. Connects to your computer via usb, has a memory slot for extra memory…
PM me if you have specific questions about it.
