How much internal memory does the DINC2 have and what's the SD card included in the box? I've read both 1GB and 8 GB for internal and 8GB and 16 GB for the micro sd card. What does it really come with? Would the SD card installed depend on where I get it from? Would wirefly for instance potentially have a different card than Verizon would include? I don't see how these specs can differ so much. Thanks.
