T-Mobile recently ran a commercial that states that they offer data plans starting at $10 a month... Well, I went and found out what that means: $10 for 200MB a month. I then installed an app on my phone called "Stats Free" to calcuate my data usage, cleared it's logs, deleted all my local email cache and then I synced my 3 email accounts back on, and updated a few apps that were out of date... I blew through 17.8MB in 10 minutes. Sure, abnormal behavior. However, I am a pretty heavy data user, and I wanted to get a number that represented what I might actually use in a month, without having to wait that long... Assuming I can keep myself under that much in an entire day (I mean, I DO have WiFi at work and at home... How hard can it be?), I would still require a 500-600MB per month data plan.
So much for T-Mobile's "Cheap" plans...
