I think you mean 24 GB of ROM, but I see your point..
This is ROM- does not mount as a HD
This internal memory is NOT mountable- just verified this. Removed SD card, downloaded a few large apps, and available space went from 6.3 GB to 6.24 GB- tried mounting the phone with no SD card installed, and it's a no-go. Also tried taking pictures without the SD card in, and it says to install SD card before taking any. For the sync option, the X uses "Windows Media Sync" in place of "HTC Sync" on the Incredible- tried to load some files via WMP, and that was also a no-go. So the 6.3 GB is ROM for pure app storage, no media storage capabilities at all. But that's great news- there's never been a ROM over 750 MB for app space before
So..... Let's just say, THEORETICALLY of course, that I had an X in hand, and that I MIGHT have it for the next 18 hours or so... What other kinds of questions MIGHT you guys wanna ask about it that I MIGHT be able to answer??
Edit:
almost forgot.... HOLY FREAKIN CRAP is this thing fast.. When I was downloading those apps, they absolutely flew.. Even a 6 MB app like Google Earth was completely downloaded and installed in 15 seconds- my stock Droid and Incredible took about 3 times that long to download the same app over the same WiFi G router with a cable internet connection, with all running apps killed.. wow..
