Accessories for Samsung r610?

I just bought this phone ( a href="http://www.samsung.com/us/consumer/detail/gallery.do?group=mobilephones&type=mobilephones&subtype=morecarriers&model_cd=SCH-R610ZKAUSC" rel="nofollow"http://www.samsung.com/us/consumer/detai…/a ) and am currently trying to find accessories online or in local stores for it. I was wondering if any other samsung phone had the same port as this phone? From what little I have learned it might be a 20 pin port?
