Earlier this morning we reported on a neat little trick that a few Windows Phone apps can do which is keep your Wi-Fi connection active even when the display is powered off.
That’s pretty useful feature for some people who are using a public Wi-Fi access point that requires you to “accept” the terms of service each time you re-connect. On a Windows Phone, every time you turn the display off it kills the Wi-Fi connection meaning you are forced to reconnect which can be problematic--even more so if you’re downloading some files.
Over at XDA, developer Ha Mai Tung (WinPhoneViet.com) has created a neat little homebrew app called Keep WiFi Alive which exploits the trick that some audio apps use. The app creates a fake music stream that makes the OS “think” it is downloading music, thereby keeping the Wi-Fi connection active. The app is simple to use—just launch and hit the button. To disable you can either turn off Wi-Fi in Settings or restart the phone.

The app is homebrew, meaning you’ll need a developer unlocked device (either AppHub or Chevron) and does not require interop access, meaning many of you can use it if you can sideload the XAP. It’s still in beta form so there could be some bugs and of course battery usage will presumably increase, so be warned.
