Thanks for all Your answers and patience with me. This number is 907 (and besides I already tried Fuzzyband...). So let's hope that some smart people will invent unlocking for 05.14.02 baseband (or downgrading 06.02 bootloader). So for now I will try to contact Telia (I saw some articles on the net about successful unlocking by them). But first I'll try to contact original owner. My brother made a very grave mistake, he wanted to have the newest soft possible . Too bad. At least everything else is working. As for now he can make calls through Skype and Wi-Fi. But it was ordeal to achieve even that... .

Thanks again.

Cheers.
