Actually it's the rewrite in native of ContactManager, a .NET version of a finger friendly contact.

Are you using a VGA device? You'll need to download and install a VGA theme here.
If you are using a device with a 240px square screen, you'll need the a theme that support this screen size.

What's different from other contact application:

• It can be used with fingers, no need to get your stylus. Finding contact with your finger is really easy, it's different than other software: if you press you finger on the left or right border of the screen it will allow you to select the letter you're searching for, release the finger, it will show you the contact starting with this letter. Why does it work? Human being cannot point directly to the right letter on a small screen, however human are very precise while moving their finger. So you press the screen, see the feedback, adjust the position to the right letter... and you're done!
• It's animated: the list scroll with your finger in a natural movement, the transition between contact detail and contact list are animated.
• You can set contact as favorites, they will appear in the favorite list, perfect to get a quicklist of contacts under the finger.
• You can edit your contact picture from the software, simply tap on the contact picture.
• You can customize about everything by changing the setting.ini: color, font, background image, etc...

From ContactManager here's what's new/modified:
- Native version: this version doesn't use .NET compact framework, it's written in C++.
- Faster version: I've put some time improving performance, on my device, it goes quite well, tell me about you.
- Faster display: drawing is also optimized, however, it may have some issue for advanced theming, tell me about it.
- New fade effect while calling/edit conact/set picture, this offer a better transition between application, tell me what you think.
- Contact update if added/changed/deleted from other application (including activesync).
- Memory footprint: No more .NET crap, picture of contact should also take less memory.
- Ability to remove contact picture.
- Edit contact now goes to edit page directly.
- New contact now goes to edit page directly.
- New theme packaging (a theme in one file instead of many).
- Letter bar between contact.
- New setting for non latin alphabet (coming with localization but now it's technically possible).
- SMS conversation panel: hitting SMS button now goes to an SMS page. It will allow to send an SMS display previous conversation with this contact...

Installation instruction:
- Create a new folder on your device.
- Unzip the content of the zip.
- Launch PocketCM.exe.

Note:
To close PocketCM Contacts, press for 250 ms to phone button at the bottom right of the screen. To minimize PocketCM Contacts, tap in the upper right corner.

To send SMS using PocketCM Contact, you have to hold the send button for at least 250 ms. It's a feature (that will be enhanced in future version) to avoid accidentaly send of messages.

The Requirements up here don't mention that it needs WM5/6 Phone edition. It won't work on a plain PDA.

***** [Jan 3, 2008] by Mike Krause using at&t 8525 / htc hermes
This is fantastic. I only wish it would utilize the sim card and save to and retrieve from the contacts stored on it. Thanks!

***** [Dec 10, 2007] by Nishant using O2 Zinc Windows Mobile 6
This is an excellent software. Everything is perfect. But there is a chance to improve more. There should be feature in installation which can replace default contact.

**** [Sep 23, 2007] by ecor using HTC Wizard
Top soft! Please help: When I lock the display the top bar is not showing windows but CManagers interface... Looks annoying... The functionality itself is perfect. THANK YOU.

This software is incredible ! Thank you so much- made my life easier and my PPC more effective. Highly recommend this download!

***** [Aug 24, 2007] by shahzzy using pps 6800 HTC
Just one thing, can this search for parts of contacts' names? sometimes I search by last, first, or even catagories (i enter these into the name eg. lawyer, hotel, etc..) so is there a way to type lawyer and have all those contacts with that anywhere in their name come up?

***** [Aug 24, 2007] by UROIF using Cingular 8525
Very excellent application... One of my favourite apps. Thanks very much to PocketCM.com

*** [Aug 24, 2007] by Roman using spv m700
Good contact manager, but when using view contact option, I can't see any contact details in summary. Just blank screen... (htc trinity, wm5)

*** [Aug 23, 2007] by just_jeepin using Dell Axim x51v
Just a note... it only works on smartphones! :(

***** [Aug 20, 2007] by Dan using AT&T 8525
One of the best softwares for PPC's. This is the first freeware I have downloaded, and its one of the best that I own. Great job!

***** [Aug 17, 2007] by socalpilot1 using Mogul ppc-6800
This works great... the only complaint about the phone has been solved by two programs (it was not a very good one handed phone before this program was installed). Get it and get now!

***** [Aug 13, 2007] by Omar using Kjam WM5
This is an excellent software now I could dial faster, email faster, and above all very unique way to dial, thanks for removing framework .NET requirement. It used to slow my device. Until now for using it almost two weeks. I haven't seen any problem.

This program is simply amazing, fast smooth scrolling, the animated effects are great, and most of all it doesn't take up alot of memory.

Excellent software!!! Any chance to have a similar scrolling list for music (mp3 files)?!? Thanks.

***** [Aug 2, 2007] by Chunga using Dopod d810
Wow the SMS Panel and the fade to call effect... simply brilliant!!

***** [Aug 2, 2007] by Chunga using Dopod d810
This is great. The old ContactManager was quite good, but this one just made it perfect.
- It's really fast
- Scrolling animation is very smooth
- Clever idea to put a alpha tag to separate each alphabet.
- Because there's no lag, it feels much more sensitive. I used to have the problem where every now and then it keeps pressing into the contact instead of scrolling. Never happens now!
Overall, great job, thanks for sharing!

***** [Aug 1, 2007] by Nadz using Dopod 818Pro (black) or Prophet
Excellent program.. A wonderful update.. Works very well with my Dopod running WM5.. The fade effects, flip to sms functions surely beats all the other contact manager softwares.. This is the best so far! Good job! :)
