Stagefright and Me

I got an e-mail a couple days ago for my unlocked Z3C and a second one today. Since I only have a Bell branded device I was surprised to see an OTA update today. Took me to Lollipop 5.1.1 but did it resolve the Stagefright exploit?

Zimperium and theAndroidDeveloperCH say no; Lookout says yes and I'm not sure what Trustlook is indicating. The Verge is reporting there is a second patch coming for Nexus devices - and hopefully everyone else. For now I'll keep my MMS not auto loading. Nice to know Sony is on the ball though.
