How do i get the iphone slide to unlock on my sprint HTC Touch?

Please i need some help. I can lock my phone but i have to have a pin to unlock, to me that takes up too much time. so i just leave it as it is and it randomly calls some of my contacts. So please that could be dangerous! I can't seem to find any good software specifically for my phone. I registered to ipmart.com but that hasn't helped me much. when it comes to customizing my phone, my brain just can't comprehend for some reason. haha I have an HTC Touch form sprint, windows mobile 6.1, and it is starting to get really boring because i can't find any good games. or fun software so if someone could give me some instructions with some links I would really Appreciate it!!:) thank you
