a bit more generic question on the current (even cutting edge) state of Qt for N900.

How does the freshly released "Qt SDK 4.6.0 RC1" relate to the "Technology Preview for Maemo" ? I believe the latter is based on 4.5 still.

Also, does any of them contain the classes from the QtMobility project ?
If not, what's the best way forward to have them available in one or the other ? Any help/HowTo for it ?

What would be the best platform to start ? the SDK 4.6 RC1 or the Maemo specific Tech Preview ? What are (current) advantages to either of them for future proofing N9x0 developments ?

I can see the generic Qt bits are pretty well documented but the Phone related bits are still in heavy development, looking at the change dates in Git

I really would like to use the QtMobility classes, specifically the bearer class for my -planned- application. I rather not go too deep into the standard platform classes if I can avoid it. Unless I have to of course. But looking at what's on the table (and coming), I should have enough with Qt.

But it looks early in the game to 'want it all'. I'll certainly need help to put the pieces correct together, both on the SDK/development side and on the device side.
Thanks.
