Another useful tiny utility comes from XDA Developers, called VAlert.
This is addressed to all HTC Windows Mobile users who face the annoyance of the device vibrating constantly when using a long ringtone on an incoming call. Non HTC device support is promised in future updates.
After downloading and installing this application to Device, you can access it only through a file manager (like File Explorer) by navigating to DeviceProgram FilesVAlert. Folder contains the executable which you can use to test your vibration pattern, which is described/programmed by the contents of the file script.txt. Basically this file contains a set o numbers, paired in groups of two, the first number describing the lenght of the vibration and the second one describing the pause untill the vibration in the second row. Pretty simple! You can create a rhythm vibration pattern to suite your ringtone or you can easily create a simple and short pattern that suits your needs.
