very interesting read and anyone using apps on thier phone should pay attention. http://online.wsj.com/article/SB10001424052748704694004576020083703574602.html?mod=googlenews_wsj this links to a very informative chart listing the apps and what info they collect and send http://blogs.wsj.com/wtk-mobile/
This does not surprise me at all, I know its a lame reference but Facebook's "groups" and "pages" and "app's" kind of do the same thing.
Yeah smartphones are an easy way to loose some PII. Bluetooths are an easy way to loose that since they can "hack" into them from a distance without touching them.
Good thing I'm still using a 6 year old phone, too bad we are upgrading next month though, really want a nice phone. Ehh...
