We already have hundreds of Symbian-based phones on the site, so having a symbian freeware site linked is kind of useless, unless it's specific for the n81. Nokia uses the s60 platform, so linking to that site on the Nokia symbian phones would be good.
However, after viewing the link, I see that it's for n81 software only. So I think it should stay.
Links should be deleted if they don't have anything to do with the product itself, IE, linking to the Symbian site, or Nokia's home page.
If it is either a page, or a whole site, dedicated to the product, keep it.
