Hi Everyone, I just added a 500mb data plan onto my iPhone two days ago. Today I checked the usage and I'm at 900mb. I would like to know how it is possible to exceed my limit in two days by that much?! I've had a data plan in the past and only used 200-300mb per month so this is absolutely ridiculous. I'm using an iPhone 3GS on iOS5. All I did these past two days was download instagram, email messages, and use Safari.
