I know you can monitor your Cellular usage through the Settings/General pane, but is there a way to track how much WiFi usage your using?! Im just trying to be a lil smart here before I purchase a data plan, and im curious how much internet I take in. I know that I would use WiFi shots more often, but there are times when they aren't always accessible, and im just wondering if it would be even worth it to consider the 250 MB plan. Is there a simple app out there that can do this?! If so, whats the name, Im having no such luck finding it.
