Unfortunately I haven't had the Keybo for quite some time (I'm an Android fan now) so I can't be sure which ESN I meant. I don't think I would have compared mine to the box or CDMA workshop, probably one in the battery compartment.. but I don't know if it would have been labelled correctly as you suggest.
The change from @par to @microbrower is all done in NV Edit on the Data tab, and that's only if you want to gain internet access to your java apps.
I should also clarify what I meant when I said "I blacked out @par. in the 2nd screenshot of the data tab". I meant that I accidentally blacked out @par, instead of just the phone number. If that wasn't obvious to people already.
