A reason to downgrade in Pr 1.2: to have a usable autocorrection for French 
Fortunately, we have the Swype keyboard but it's a sad situation.

Not possible is the default answer for marcaurell.
However it is possible if:
a) you have R&D certificate in your device (which only Nokia employees have)
b) you use software downgrade exploit (which is not publicly available)
, so i don't think, it will never happened. Been there done that... I think there could be some software to do so, but it's only available for Maemo/Meego team.

you need be in normal mode (not open mode) and clean/erase the cert-sw..., and you can downgrade the APE side (not the CMT side)

In normal mode you have read&write access to CAL. So I think downgrade can be done with writing some old cert to CAL, then rebooting & flashing old version of fiasco.
