As posted earlier from the link at Sprint's site for the Evo3d:
Sprint - HTC EVO? 3D
Look on the right side and click on the "View full specs" link.
There you will see that it is 4gb internal memory and 1gb Ram. Not sure why htc's website said that. Maybe it's just that Sprint ordered a version with more internal memory.
Look at the bright side guys, this does have FM radio! LOL
Ill be getting this on launch day. The screen and processor are good enough for me. I will be using my upgrade.
Hopefully detailed specs will have better news and benchmarks/comparisons to the Atrix will be competetive. It is rumored that Sprint will be getting the Atrix as well too.
