hmm... I don't see a system version in my "About Phone"
Here's what I have:
System Updates - says I'm up to date
Status
Battery Use
Legal Information
Safety Information
System Tutorial
Model Number - DROIDX
Android Version 2.2.1
Baseband version BP_C_01.09.07P
Kernel version 2.6.32.9-g23d7ba5 w30471@il93lnxdroid08 #01
Build number: VZW
MOD/ROM Version Liberty v1.0
Is it somewhere else?
Just an FYI...
About phone displays whatever is in /system/build.prop (which has been COMPLETELY replaced by whatever ROM you're using.
I believe the ONLY item that isn't pulled from the text file (build.prop), is the kernel version, which is the actual version of the kernel you are running...
Also, you are confusing the version of Android (2.1, 2.2, and 2.2.1) with the Moto update versions (2.3.9, 1.2.13, 2.3.15, 2.3.151, 2.3.320, 2.3.340).
The Maderstcok update will upgrade you from pretty much ANY previous version up to the latest (android version 2.2.1, update version 2.3.340).

Edit: And just so you know, the version of the kernel you listed is the 2.3.151 (2.2) version... after you maderstock, then re-root using z4, then rebootstrap, etc., you'll be on the 2.3.340 version: 2.6.32.9-g55626e1
