Here is a look at how many megabytes of data I have used in the last seven months.

I expected December to be high since that is when we host the onething conference. Everything gets progressively more erratic during the last few weeks leading up to onething, and flat out ballistic once the four-day event starts. But I am shocked to see October as my highest month of usage. That was the month Anna and I took a week-long vacation to the Ozarks and my phone was literally turned off for seven days.

Being able to tether my iPhone to my laptop, as cool as it is, is not worth the more expensive plan and the $20 a month tethering fee. So I won’t be keeping my current “unlimited” plan and will instead be downgrading to the 200MB for $15 plan. Even if I do need an additional 200MB on occasion it will still just be equal to the $30 I’m paying now.

Here is a roundup from Macworld on the new data plan changes. Here are directions for how you can create your own iPhone data usage report. And here is Neven’s report, from whom I was spurred to post my own.
