While there still is not a price to be found, the 9@9j has been officially released and with that comes the full list of specs. Of course we have already seen the unique battery system. The 9@9j contains a standard Li-Ion battery that offers 8 hours of talk time and 1 month of standby and a single AAA battery that serves as a backup and offers up to 2 hours of additional talk time and up to one week of standby time.
As for the rest of the specs; the 9@9j features Quad band GSM (900/1800/1900/850 MHz)/GPRS connectivity, a 1.3-megapixel camera, a microSD card slot, USB 1.1, stereo Bluetooth A2DP support, an FM radio and a 176 x 220 color TFT display.
The 9@9j has been release (as of now) only in the Asian market. No word if or when this will ever be available elsewhere. The whole backup AAA battery option seems like something that could easily be adopted into other cell phones.
