If I want to send or recieve pics I have to turn them both on, why is this? Is there a way around it? Is it like this on all iPhones? When I first got it and activated it I used it on edge and it all worked fine, pics, videos everything and I never got charged, then I used that APN changer website and it didn't work so I tried to uninstall through their website and it said on iOS 4 all you have to do is go to settings and turn off cellular data, I did but now no pics, someone please help out, should I just restore my iPhone and avoid the APN changer website? Thanks for any help, Ethan.
