Thaf is really a pity and you have my full compassion.
Your alternate is a nice toy for me (see ubiboot),
but cannot really replace the N900!

And guess what:
it HIT me too a few days ago.
On boot:
'Could not establish network connection. Contact service.'
That's it. No cellular function anymore.
--and I do not parcours, but kept it like my beloved and treated it like a raw egg (usb is still fine after more than 3 years daily usage)--

Grabbed my replacement out of the wardrobe, flashed, installed backupmenu, copied everything, ran recovery, let mutiboot flash the right kernel on first boot and I am up again with my No. 1.
The other got a reflash (eMMC clashed at 32768kB, but cleaned/partitioned) and installed CSSU thumb. Installed also AIFS with cellular modem disabled to get rid of that boot-blocking message.
Waiting to be used as tablet, mail/browsing station at home (wife/kids)...

Waiting also for Neo900!
joerg,dos1,nicolaus and all other involved, please hurry up. Our N900 are starving...
