My girlfriend bought an iPhone the day after I did, but she didn't get a data plan like I did (I got the $30/month 6GB plan, which is overkill for me, but the other plans were ripoffs). She didn't get a data plan because she wasn't going to use her iPhone for any of the features that needed data, because she always has access to wifi, either at home, at university, or at work. But in the week, her iPhone seems to be using data on its own. She has received 15kb and has sent 58kb. At $0.05/kb, that's only $3.65, but stillwhat could have been using data? She has moved all the applications that do use data to a separate page that she never goes to, and has changed all the options so that she won't access data. She is positive she hasn't accidentally pressed the Safari app, for instance. Any ideas?
