Everyone knows the Wifi issue with Windows Phones right? You lock the phone and the wifi goes dead wasting battery and your data plan. Not anymore! An app just hit the market called Keep Alive and it solves that issue by keeping your WiFi active when your phone is idle.
I have tested it and it works like a champ. When you pull it up it may seem to have odd details and screenshots but you have the right app download it anyway. Open it up once and you are all set.
This is a free app but you can support the time and effort it took to make the app by clicking here.
