So I finally got an Android-based phone. I thought waiting for Ubuntu/Firefox stuff to be released but my current one (Bada-based: never ever) died.
First, I learned that actually you need to lock your phone with a Google account for life. It just confirmed that the sane proper first steps with this is too remove anything linked to Google.
First place to go is to F-Droid. From there, instead of getting tons of shitty freeware from Google Play/Apps/whatever, you get Free Software, as in freedom even though I like free beer.
Using ownCloud? From F-Droid, get DavDroid. Yes, that works perfectly and is easy to set up, unlike the Dav-related crap on Google Apps. The only thing you have to take care of, if your SSL certificate (trendy topic theses days) is self signed, is to make a certificate the specific way Android accepts them. For now, they recommends to do it like:
