This application, made by XDA member oldsap, prevents your phone from sleeping. That will make it possible to keep your WiFi connection up even after locking your phone. Also, other scheduled applications will be able to run on background.

This little application won’t allow your Pocket PC to go to sleep.
Ever got frustrated when you are connected to Wifi and you get disconnected because your device goes to sleep mode? Then this application is for you.
Just launch DontSleep and either click on CLOSE to exit the application or HIDE to use it.
DontSleep Wifi will automatically turn on your wifi while preventing your device from going into sleep mode.
Continue to the application thread for download._________
