So I just noticed something odd on my iPhone 4. My iphone 4 is jailbroken (as can be seen by the screen shot). Occasionally, when I close an app, open an app, or unlock my phone I will see an ad, and I caught one with a screen cap. The screen crap is from unlocking the phone (which I had locked on the messaging ap). You can clearly see an ad at the top of the screen as the messaging app (the stock messaging app) is coming up. Has anyone got this? I'm a little worried I might have some sort of spyware on my phone or something. I'm thinking about resetting the phone and putting it on stock firmware. Suggestions? Anyone else had this issue?
