Update after 2 something years: after thoroughly unpleasant experience with the UPC's customer service, like *completely* ignoring my reports for months until *I wrote a f*ing paper letter to them*, then asking several times for some details that I already provided them and ignoring my replies and asking the same details again and again, finally under pressure confirming they've received my previous e-mails (but apparently not reading them), and then... nothing happened for months. (sorry for the rant)
And then, suddenly, Wifree started to work and keeps working for maybe half a year by now, after almost 2 years of not working. Not that I need it that much, and I certainly *do not* recommend UPC if you have a reasonable other choice. And it does not solve the Android unable to select an AP issue.
