Ok I have noticed something on my Samsung captivate from AT&T, when I am on a wireless network the ads in my apps are harmless like join youtube, or click here for the new game. Yet when I am on the 3G network I get Hey big boy text me, or click here for playboy. Can anyone explain this? I did a test by running an app on wireless and got the good ads, then turning off wifi and ran on 3G the same app and got the bad apps. Is 3G that bad?
