Can you explain what you mean by "realization" and how USSD is broken in PR1.2?
I did not have to do anything but install the ussd-widget.... Works 100% for me - from the widget and from the phone interface *111# gives me all the USSD functions from Vodacom (South Africa) - works 100% - everytime But as I said, got the phone, updated to 1.2 (over Wifi) - restarted and it is just working for me (no library dissasembly - or nothing)... Just installed the ussd-widget from extras (app manager)
