Sure, it's great you guys point him to the read-me-first stickies but they have so much information in them it would take a long time for him to find what he's actually looking for.
The iPhone-style slide to unlock has been re-created for windows mobile, it's called S2U2. It can be found here:
http://s2u2.ac-s2.com/
Normally, I'd just give you a direct link to the .cab file to install on your phone, since you don't have a data plan, you're out of luck there. There is no extremely simple way beyond that.
You'll want to download the VGA version (because the TP has a VGA screen). Save the .cab file anywhere, your desktop is fine.
Plug your TP into your PC, connect via activesync (or wmdc, whichever you have). Open up the following on your PC:
My Computer -> Touch Pro -> Internal Storage -> My Documents
Copy the .cab file for S2U2 to that folder. You can disconnect your phone after it's done copying.
On your phone, now:
Start -> Programs -> File explorer
It should automatically open up to the My Documents folder. Scroll down till you find the .cab file for s2u2, tap it to run it. Install it to internal storage.
Then you'll see it in Start -> Programs -> S2U2 and can run and configure it from there.
I'm not going to provide any support past this, it is what it is... you can do it.
