Very badly researched articles and Summary:
Symbian Foundation closing does not imply that Nokia will stop Symbian Development.
Symbian 4 being transformed from an incompatible system into an upgrade path from Symbian 3 does not make it go away except for the name.
And another one:
"Symbian 3 made it onto a couple of phones, but no one really noticed or cared"
The first Symbian 3 device was only just released (N8) and reviewed by the usual websites, and 2 more are announced and prototypes released and shown at the Nokia Fare (C7, E7).
I'm to lazy to actually read the whole articles but there's probably more nonsense.. bad Journalism.
