I was recently searching about this setup. Closest I found (off another website can't remember) was the Sena SM10.
Just ordered a Spartan tempered shield for $6. Fall91 didn't work but Summer80 did which is 80% off.
^Wow.. Really? I'll do that at work! No more killing my batt! Thanks
Edit: and fail... killed the phone. I guess it doesn't work. :(
I roam all the time, I've called them to tell them their reception blows, I've asked about the Airave (not that I want it, I like my internet bandwidth thanks...), and I've never received a notice. Not my god damn fault their shit is shitty... K...
I'm not getting my hopes up too much, the price will sure hurt... Is it March 2016 yet... http://phandroid.com/2015/09/07/sony-xperia-z5-ultra-rumor-march/
