Hello!
I need answers to these questions:
1. Is it possible full integration with Kunena 3.x? As on the older versions (Kunena plg).
2. Design and construction of JS profile can be changed as in the old version (2.x)? I dont like Facebook design :(
1)As far I know Kunena dropped support for JomSocial since version 3.0, however it still should works quite fine even with our latest release which is 3.1 now.
2)Well at this moment we don't have any template which looks like that, so you'll need some custom template which such design(I'm not pretty sure if such template exist) or some professional php developer who may create such styled template for you.
3)Sure, it should be achieveable but only with some custom SEF extension, but please keep in mind that JomSocial was bassicaly designed to work flawlessly with native Joomla SEF.
4)Generally we don't have such services, however you can always hire a professional php developer for such desk, you can find one on our oDesk section here >
