Please Note: This question is slightly based on me being a tin foiled hat with the issues that has arisen from the leaks, documents, and questioning trust thanks to Edward Snowden.
Thanks to adding my VPN service to my cellphone to improve security and stop "eavesdropping" of Verizon on my data and usage, I am questioning the trust with Twitter, Facebook, Google, and all of the major social networking applications and how they are keeping our data secure as we access their applications.
There is no notice, information, or indication that they are using SSL/TLS within their applications for Android, Windows Phone, and iPhones.
Is Facebook, Twitter, Google Plus, and other major applications have SSL/TLS enabled and coded into their phone/tablet applications behind the scenes?
