How can I avoid using data while it's on?
Well, the obvious answer would be to just turn off data, but that doesn't work for me because it needs to be on in order to use picture messaging, so I'm wondering how I can leave data on in order to use that one function, but make sure that no other apps quietly go and use data without me knowing. I don't actually have a data plan so even using a just a bit will cost me a lot, so that's why I want to avoid it. For instance, could the ios choose to update apps without asking me? Could weather get updated without me asking if I forget and leave it running in the background?
