HSDPA is 3g, Edge is technically 2.5g (same with EVDO. Though VZW and Sprint will call it 3g.) Technically, according to RIM, 3g allows simultaneous voice and data functionality, so any WI-FI berry is "3g". The new 8xxx series will be 3g with Wi-FI and GPS supposedly. Again though, its just a rumor at this point.
