If you are rolling out your application on Smartphone or Pocket PC phone edition devices, you may wish to record the device’s International Mobile Equipment Identifier (IEMI) or International Mobile Subscriber Identity (IMSI) numbers.
These numbers can be used to track what device and SIM card are being used by which user. It can also be used to ensure that the data on the device is kept unique by using the number as a device prefix within your data.
The Sapphire IMEI Utility allows both the IMEI and IMSI numbers to be read from SmartPhone and PPC2002/2003 Phone Edition devices.
You can download the latest demo version to see a fully working demo which you can reuse within your application as you see fit. This can be found on the download pages. The demo versions are fully functional and simply contain a popup message from time to time. These are ideal if you are selling your application to the client where you can be confident the application will work in practice and not just theory.
