when I got my iphone today, after activating it, the apple employee asked me if I wanted to register the phone on itunes. I wasn't really thinking, and just said, "sure" and registered, putting in my credit card number and everything. I'm now paranoid that my credit card number will be easily accessible, since they used one of the demo computers, and god knows what people install or put on them. Does apple clear their computers of data each day? Is my credit card number and iphone safe?
