title: How to measure the amount of megabyte data?
body: <p>I want to make an app that measure the amount of data I use while surfing on my Iphone over 3g network.</p>
  
  <p>Things I would like to incorporate;
  - UIPickerView (to set the amount of data I want to to use before an alert shows)
  - AlertView ( the warning that my data is about to exceed)
  - Run in the background.</p>
  
  <p>So basically, I want to be able to set the  amount of data I have on my Data plan.
  I want to set the amount of data I can use before the AlertView shows and tell me I'm soon over my set limit. And last, I want it to run in the background (multitask enabled). </p>
  
  <p>How do I make this app, and again I'm new to development so I wanted to start off with small apps like this. So please, can anyone help me and kind of tutor me in this?</p>
