Reached the point that I pay too much for a smart phone that I use only for calls and GPS, since I don't trust it for anything else. Bought my age'd mother a prepaid flip phone for emergencies a few weeks ago (she's 80, couldn't figure out a smart phone), and I was very tempted to buy myself one as well and dump the $60 a month android bill.
Yes, I keep cyanogenmod on it and update, still don't trust it. Of course even my favorite linux Mint is no longer safe... :)
