When I had my iPhone 4 with Verizon, I used roughly 300MB of data per month. I recently upgraded to the iPhone 5 and switched to AT&T. Yesterday, at the end of the FIRST DAY of the billing cycle, I checked my data usage --- 500MB! I was barely on the phone at all yesterday. I probably checked Facebook 3-4 times and refreshed my twitter feed a couple times as well. I get about 50 e-mails per day. Can anyone tell me why this is happening?
