Data Usage Per Each Phone on Plan?

[orange42]

Where can I find the exact data usage for each phone per month on my family plan online? It might be right under my nose but I can't find it online other than just going through pages and pages of the bill.

Nevermind I found it. I'm dumb. But these data numbers are not what I expected.

I haven't used more than 200 MB of data in the past 8 months. The closest I've come was 110 last month because I had wifi off for a while. If I change my plan to the DataPlus for $15 a month and then get the iPhone 4 and realize I'm using much more data could I ever end up going back to the unlimited plan? (This probably won't be necessary if I only use minimal data, but hypothetically.)
