With most bluetoothed cell phones and cell providers it's quite easy, search around a bit in these forums and you'll find it. But with some phones & providers--like Samsung and AT&T--one must go thru some fairly complex and difficult operations to get it to work. There are also some posts about the Samsungs and Nokia ITs here and there but you have to piece together the required stuff for your particular model. I did it for mine if you need help.
