After Koushik Dutta posted the Stylus Sensor API new applications exploiting these features were going to surface @ xda-dev it was just a matter of time and here is one of the first Stylus Sensor application by ZuinigeRijder. Its a lock / unlock utility for devices like HTC Touch Pro / Diamond. Its got a bit of a learning curve than the other lock application.

How to use:
* Choose your “stylus lock mode”, by using the method above
- e.g. if you want to put the TD in your pocket, enable “stylus lock mode”
- e.g. if you have your TD lying on the table, disable “stylus lock mode”
- e.g. you can also use always the “stylus lock mode” when your are fine to take out the stylus for unlocking (you do not need to operate the Power button anymore)

What does it do:
* There are 2 modes, “stylus lock mode” enabled and disabled
- Mode 1 – enabled – stylus in = phone locked
- Mode 2 – disabled – stylus in = phone not locked
* You can toggle the “stylus lock mode”, by taking OUT the Stylus and putting it back IN within 3 seconds
* In fact the second mode permits not to use the lock functionality, in order to use your fingers on the touchpanel and hardware buttons, rather than the stylus.
* On startup/boot/reset it will be always unlocked and “stylus lock mode” is disabled
* It will always be unlocked, when the Stylus is OUT
* It will always be unlocked, when on ACPower/USB power
* It will always be unlocked, when the program is exited
* In “stylus lock mode 1″, putting the Stylus IN and on battery-power, the touchpanel and all hardware keys will be locked
* In “stylus lock mode 1″, when switching to battery-power and the Stylus is IN, the touchpanel and all hardware keys will be locked
* Vibrate once when switching to unlocked state
* Vibrate when switching to locked state and/or “stylus lock mode” enabled

How to go to sleep mode immediately AND locking the phone when in “stylus lock mode”
Press the Power button and insert the Stylus. You will feel a double vibration when the phone gets locked. In this way you do not rely in the Windows settings for going to sleep, it will go to sleep immediately.

Unlocking use case when “stylus lock mode” is enabled and e.g. a phone call is coming in.
* Option 1 (when you want to use the Stylus or have place to put it somewhere):
- Take the stylus OUT and keep it out
- Answer/Reject the call with the TouchPanel or Hardware keys
- When done with the call, put back the stylus IN
* Option 2 (if you do not want to use the Stylus and have no place to put it):
- Take the stylus OUT and put it back IN within 3 seconds (”stylus lock mode” disabled)
- Answer/Reject the call with the TouchPanel or Hardware keys
- When done with the call, Take the stylus OUT and put it back IN within 3 seconds (”stylus lock mode” enabled)

Unlocking use case when “stylus lock mode” is disabled and e.g. a phone call is coming in.
- Answer/Reject the call with the TouchPanel or Hardware keys, because they are not disabled

Note that in the above 2 use cases, taking the Stylus OUT and keeping it out for 3 seconds will always work, so you do not need to remember the “stylus lock mode”. I am looking into a Lock indication in the notification area (working on that, not yet part of v1.x).
