Now that AT&T will let you see your iPhone data usage by month (to help you pick which of the new data plans to get - don’t worry, you’re grandfathered into the old, unlimited one) I’m pretty sure I’m legally required to post my usage.
This is all the data they’ll show me. I’m at a loss as to why January was such a spike. I assumed I used data more while traveling, but the graph does not support that theory in the least. I don’t see anything in my calendar that would explain this. Maybe I bought a movie on my iPhone? I sure don’t remember doing that, though.
Dan Wineman says: “January was my highest-usage month, too. Nearly double the second-highest month. I think it’s because I was in Oklahoma for the holidays with no broadband, and the graph represents what was billed in January, not what was used.”
What you see above is my own graph of AT&T’s data. AT&T’s report shows billing months; I converted these into real months. Since my billing period starts early in the month, their graph causes December’s data to show up as January. Dear AT&T: no customer thinks in terms of billing cycles.
