The E61 had S60v3 and it was weird but really very usable. A device that was in many ways ahead of its time. VoIP, Webkit, fully usable IMAP email.
But Nokia smartphones were essentially shut out of the US phone market by the toxic carrier-exclusives situation and their corrupt allergy to on-device Wifi (Nokia couldn't get a major carrier to take the E61 until they repackaged it as the E62 without wifi)
