It may work on other devices. If you're running Windows Mobile 5.0 Smartphone or Windows Mobile 5.0 Pocket PC Phone Edition, give it a try. If it works, let me know so I can add your device to this list.

TxtMan requires the .NET Compact Framework 2.0 to be installed on your phone in order to run. It's free, and many other Windows Mobile programs require it, so it's a good thing to have. To download it, go here.

Installation instructions:

• Make sure you have the .NET Compact Framework 2.0 installed.
• Right-click the "Download TxtMan" link above and save the CAB file to your hard drive.
• Copy the CAB file to your phone. Any place will do. I'd suggest Program Files.
• Using the File Manager on your phone, open the CAB file. This will begin the installation.
• After the installation is complete, you may delete the CAB file, or you can keep it on your phone so that you can beam it to your friends :)
• If you want to uninstall TxtMan, go to Start Menu > Settings > Remove Programs.

Notes:

• As long as the program is running, it will receive SMS messages, and it will prevent the built-in messaging application from receiving them. If the program is not running, it will not launch itself when you receive a message. It must be already running to receive SMS messages. There is an option in the options screen to start TxtMan when the phone boots up.
• Due to the way Windows Mobile manages memory, you may find that if you have been using a lot of different programs on your phone, or doing something that requires a lot of memory, that Windows Mobile will automatically shut down TxtMan without warning. It does this to free up memory for whatever you're currently doing. Unfortunately, TxtMan won't receive SMS messages after it's been shut down. If you've been doing a lot of work on your phone, you should check to see if TxtMan is still running.
• You won't get message notifications like the built in messaging app gives you, but the program will play a sound, vibrate, and bring itself to the foreground when a message is received. If the phone's ringer is off (silent mode) or you are on a call, TxtMan will not make a sound when an SMS is received. However, it will still vibrate, unless you turn that off in the options.
• Due to the peculiarities of the .NET Compact Framework, when the focus is on the conversation window, pressing up and down on the 5-way pad scrolls the conversation, but will not move the focus back to the text input area. To move the focus away from the conversation window, press any key except up or down.
