i have the nokia 5165...real nice phone and you can get downloadable rings.
The nokia 8260 and 3360 seem nicer since you can also get graphics and such.
A friend of mine just re-upped and got an Ericsson R300Lx for free. It has downloadable rings (even though i cant find it), voice activated dialing, vibra-ring, and some other sweet features. Only problem I had with it was that it doesn't have any customizable batteries or faceplaces. Oh, it also comes with an $80 MIR so, in effect, you get the phone and 80 bucks for re-upping your plan. We just did that here in Pittsburgh less than 2 days ago.
