Help Metro Ascend missing Internal Memory

[wlawlor63]

Things that don't make sense.
The Ascend specs show the caps of the phone to be: RAM - 256 Mb
Flash - 512 Mb
768 total

Android Asistant shows: Memory Info(RAM) - Total 178.83 MB
Phone Space Info(ROM) - Total 166.62 MB
345.45
768 - 345 = 423 MB missing storage. Does anyone know where this storage has gone, and how might I get it back??

Thanks for the help
