There is a rumor that Nokia RM-670 is making its appearance on FCC. The device is still unofficial, so we don’t know pretty much about it.
Nokia RM-670 seems to be a standard handset, which features a 3.2-inch AMOLED display and 1GHz processor. It also goes by Zeta and the operating system of choice may very well be the new Symbian Belle OS.
The handset might be supported by both AT&T and T-Mobile 3G bands.
