Latest O2 Xphone ROM firmware?

[Guest goodnite]

Bought my Xphone a few days ago and when I checked the "About", it says the following

Microsoft Windows Powered Smartphone 2003

Version 4.20.0 (Build 13349)

Radio Version 1.13.01

© 1996-2003 Microsoft Corporation.

All rights reserved.

Available Storage 1.84 MB

Total Storage: 30.33 MB

Available Memory: 6.06 MB

Total Memory: 17.76 MB

Processor: ARM OMAP 710

ROM update versions:

Operator: 1.10.18.3

Manufacturer: 1.11.18.23

Microsoft: 4.20.13349.0

Language: 1.11.18.23

File System: 4.20.13349.0

Question: According to Xphone website, it says the Xphone comes with 64MB Flash and 32MB SDRAM. Yet the above numbers looks strange.

30.33MB = 32000000bytes of (32MB SDRAM) I suppose. Where is my 64MB Flash? What's Total Memory (17.76MB)? Is that FLASH?

Also, the ROM update versions: Operator:1.10.18.3, is that my Xphone's current ROM version? It looks newer than what's been discussed in the forums here. Is this correct? If someone can show me how to back it up, I suppose I can make it available for other Xphone owners. :P
