it was unable to upgrade PR1.1 to PR1.2 through wifi
I saw the yellow square notification to upgrade but it was not able to do it.
I had to download the upgrade file to my computer and install it through USB

it was the same issue like this

yep, have more than 500 contacts in my phonebook with multiple entries but none on my SIM. i backup on my sd card when i use the backup feature on N900 and it doesnt backup the phonebook. it doesnt mention phonebook either when you bring up the backup app on the N900

p.s.: (i keep saying N900 and not "the phone" since the argument about "phone" versus "mobile computer" isnt settled yet!)...

I have installed Nokia Ovi Suite 2.2.1.23
As I was told before, backups from that suite might be some gb
my backup through the suite says 80mb
is that normal?
when I am in mass storage mode, I see Nokia N900 device is around 500mb
Also in settings / memory / details I see Total size 27,22mb
in use by system 228mb
user files 790mb

How is it possible the backup to be only 80mb ?
Also when I try to retrieve and backup messaging I get a message saying that "messaging not supported with this version of device software"

so, the 2 questions in brief
1. is 80mb of backup normal? (I removed all photos, videos, mp3 from the device manually)
2. how can I backup sms messages?

mine was a few gb because of nokia map data and sygiic map data too, and other applications that i had installed. in case you dont have these, then it sounds about right. sms messages is part of conversations, and gets backed up when you back up either on OVI suite or the phone backup feature (which i would ask to do nevertheless)....

it didn't allow me to backup sms because of "messaging not supported with this version of device software" message. I tried both OVI Suite and Nokia PC suite.
Finally I made the OTA update to PR1.3

next thing is to try meego and android
