Been running it all day now. Seems to be one of the other variants: no full-size keyboard in portrait mode etc.
Nothing too exciting so far. I had been running .106 because .113 battery life was too much of an issue for me. I don't see a massive difference between this and .106 - possibly lightly slower? memory leak pretty much the same as the others, but battery life much much better. I've had about 1 hour 50 mins talk-time and an hour + browsing, and there's still 35% left Other versions would have had me reaching for the charger.
There is someone running a hybrid of .122 on a 9500 (RobinM from the the VF UK e-form) and will check this out.
