They're already sending out your info from apps in the Android market! Didn't you see the Wall Street Journal front page report a couple of weeks ago? It was discussed in a few threads here. Pandora was the BIGGEST culprit of selling your personal info and location to others. I have since uninstalled Pandora.
Never assume an app is safe because it's in the Android market. That's a big difference between Apple and Google. Steve Jobs acts as your daddy to keep you safe. Google apps market is open and unristricted...let the buyer beware.
And even Steve Jobs doesn't do a good job. The Wall Street Journal article said many apps in the iTunes store also sent out personal info (yup, Pandora came in number 1 again). Apple denied to comment on the article!
