I brought a belkin sports armband for the ipod classic to use with my N95 and it fits perfectly. The N95 and the Ipod classic are almost the same size. Very happy with it, can see the phone and control it through the clear cover. http://catalog.belkin.com/IWCatProductPage.process?Product_Id=404775
I actually brought mine over the counter at my local Maplin but there is various places if you do a google search.
Just used it in the Great North Run and it was really good.
