The Nokia 6300i (might be the 6301 actually), 6650 (Nokia’s first 3G phone, but knowing Nokia they might recycle the name) and 7070 (no Nokia has ever had this model number) have been unearthed by the German site NokiaPort.de
They also mention the 7070b, that is just the same device as the 7070 but for a different territory.
No specs, no pics, just a “hey, this will come out some time between now and the end of time.”
