Hello all, A few months ago I accessed some websites containing erotica from my iPhone 4. These sites, as far as I could see, were perfectly legitimate and legal (except that there may have been one that I had trouble back-spacing out of), and contained mostly writings. However, I'm now worried, based on horror stories I've heard, that visiting them may have caused me to inadvertently download child pornography on my phone, either by a trojan horse or by drive-by downloads. Is the iPhone susceptible to either of these two things, and if so, is there any way I could do a 7-pass erase just to be sure? Thanks.
