Ok, so an e-mail was patiently waiting in my inbox claiming to have some details on the recently certified SPH-M900. I have no idea if it’s true or not but these things somehow seem obvious. And no, he did not say anything about the OS.

3 megapixel camera
microSD card slot
Bluetooth
Wi-Fi
PTT

Pretty mediocre specs, if one has to believe. Maybe we’ll hold for some more time until something substantial surfaces.
