Not that data is a big issue to me since I have unlimited with AT&T, but I am just wondering what is using up so much data on my Iphone 5. I'm mostly always on WIFI. I tested the LTE for a little bit but haven't really used it for much other than just browsing websites. The only thing I can think of is ITunes Match. I use that but I must have only used it off WIFI for maybe a total of 10 songs. So I can't attribute all the data to that. Anyone else seeing a high usage of data without complete explanation with this new LTE?
