It appears that Nokia is developing a new phone series. Evidence from two different sources suggests that a new T-series of devices could soon join (or perhaps replace) Nokia’s current C, E, N and X families.
The first reference is found within the Nokia Ovi Publisher Tools where it is listed as Symbian^3 device. Unfortunately, that’s the extent of the information there.
The T7-00 also appears in a user agent profile (UAProf) file on Nokia’s website. It reveals that it will be powered by Symbian^3 and come with GSM/GPRS/EDGE/WCDMA/HSDPA connectivity, Wi-Fi, Bluetooth, and a display with a resolution of 360 by 640.
There is no indication as to when we Nokia could announce the T7-00.
