Just saw this at Nokia Business Software Downloads


S60 (Nokia E90)

Nokia S60 BlackBerry Connect 4.0 vers. 8.9.1(.SISX, 3,93 MB)
NOTE: You need software version 200.34.73 on your device. This client is for BlackBerry Connect 4.0. You may use the BlackBerry Connect Desktop software for your PC (see below) to provision your phone but it is not necessary because BlackBerry Connect 4.0 is able to perform Over The Air Enterprise Activation.



and note the size 3.93MB !!, almost 25% more than previous version. Hopefully got lots of new features! :D
