Hey, guys... I did the Jellybean update to my MAXX, and I too lost the ability to read texts via Sync. I have the "standard" original version of Sync in my 2010 Fusion. I was just on a chat with Ford, and they checked to see if there were any updates for my system, and they said no. They also told me that it wouldn't work with Gingerbread or ICS, but it of course did-- it was only after Jellybean that it stopped working. (What was even more worrying is that after specifically telling the guy that I have an Android phone, he asked me which version of iOS-- 6 or 6.1-- that I had on my phone. *Facepalm* Ford really needs to get their act together.)
I've been happy with the Sync functionality up until now. Everything worked great with my Droid X and then my Razr MAXX. This is
really frustrating, however. I tired a factory reset of Sync, did the update (of which there really wasn't one), removed and re-paired my phone. No joy.
