I have been looking for a good screen lock. I tried using S2U2 and it worked fine...until I noticed that when people called me, it would ring twice and goto voicemail 70% of the time.
I also noticed that you cannot use device lock like you could on the mogul (have it on the today screen)
I stumbled upon this on youtube (sensor lock) and it works beautiful. the video shows it being used on a HTC Diamond but it works perfect on my Sprint Touch Pro.
I take no credit for this app, I just figured I would share it with you guys seeing how I found nothing about it on here.
