I'm concerned about my iPhones data usage. My usage patterns have not changed, mostly doing Facebook and twitter plus imore and I've used almost a gig of data since Friday when I got it. Most of my apps and updates come from the iTunes program on my pc and I'm not doing anything in the cloud. With my Galaxy s3 I hardly used 500mb a week doing the same activities, and I kill off all apps when I'm done. Is there something I'm missing here?
