Microsoft has just outed Data Sense, a new app for Windows Phone 8 that helps ensure you don't burn through your data plan. On top of tracking your usage app-by-app, it compresses every single web page you browse to keep data consumed to a minimum, and also sniffs out WiFi hotspots when they become available. The app features a Live Tile to give an ongoing saga of the megabytes you've consumed and will warn you near a preset limit. Redmond claims the hotspot sniffing and compression will let you consume 45 percent less data "when compared to the competition" -- likely a reference to iOS and Android, which already have a similar feature. Data Sense will arrive first on Verizon this fall, but there's no word yet on when other carriers will have it. To check the PR, go past the fold.
