Hi All - Wanted your opinion about security on the iPhone 3G. In particular, what are your thoughts about using iPhone to do online banking and such? If I am on my home wifi network (which is encrypted), would browsing the web (online banking, etc.) be just as safe as if I were doing it on a laptop using the wifi? What about when I'm using 3G, EDGE, or some public wifi (i.e. Starbucks)? Thanks for the feedback.
