The OneClickFlasher is updated today.

You can find it here.

Here is the news from Nokia:

The Beta2 firmware release is now provided in the OneClickFlashers. The Beta2 release provides a number of bug fixes and functional changes, along with the addition of a number of features and applications (Nokia Store, a Twitter client, and a WiFi hotspot application among others). 'Developer Edition' marking and the SDK installer have been removed.

I wish it can turn my brick N950 on again...
