get Unique phone ID using IMEI or GUID

[kieran]

Regarding the GUID issue:

All GSM phones have a unique identifier (IMEI) that is very often available from the system settings. It depends on the a number of different platform-specific issues (A) whether the IMEI is available to Java, and (B) how to get it if it is.

A really cool project for someone might be to create a system that creates a unique ID for a phone with a protocol like:

1. Attempt to fetch IMEI. 2. If unavailable, attempt to fetch another unique identifier (Phone #, Manufacturer ID, etc). 3. If no unique ID is available, create a GUID.

There's a good page online with the invocation to fetch IMEI numbers from a bunch of different manufacturers here:  http://mobilepit.com/10/how-to-get-imei-number-in-j2me-javame.html
