As promised here my feedback.
1. Since I installed version 3.0, connection issues are solved and everything is working fine.
2. The process to receive 3.0 is far to complicated.
In the change from 2.2 to 3.0 you obviously require to completely uninstall version 2.2 and then install 3.0.
Which means, when clicking on "check for updates" on version 2.2 it always tells you your software is up to date.
This would be fine, if you actually could easily compare the version by visiting the SE website and check for the version they offer there. But what ever way I've chosen to look for the newest version, I couldn't find it.
So, to retrieve the newest version, you actually have to go on google and type in the search bar "Sony Bridge for Mac download" and then you find the link to the actual version.
I noticed that before, since the change from branding the phones SonyEricsson to only branding them Sony, the navigation on the site got much more complicated.
If you'd like to know more, drop me a message and I give you a few examples.
