With all due respect to "coderman", but I think that I'd like to see some proof of what he's mentioning. If what he says is true, someone has created a system that automatically man-in-the-middles all mobile connections, and then intelligently exploits them with increasingly more sophisticated exploits? Please forgive me if I'm a little skeptical.
Friend of mine came back from Defcon complaining of some of the exact same symptoms as those listed by coderman and said he'd be DBANning his phone later.
funny story, there was an android SW upgrade on verizon that weekend. i was halfway across the world and i accepted. i guess i'm boned! :( powerful mitm
Yeah, I hate to say it, but as an android user half those symptoms are typical, especially in heavily congested areas, and the other half could be explained with a half-cooked update, which is also typical.
