Every time I see something like this come up, it really makes me wonder how many other apps out there are doing the same thing and getting away with it. Unless you root your phone and use something like the mentioned android firewall, or go whole-hog and install Cyanogenmod, what chance do you have to guard against this? I assume ios users are likely in the same boat, but with even less chance of recourse.
iOS users have no chance at all. There is no freedom in the iThings. Apple is in strict control over their users.
