Oh, and BTW, the serial number portion of an IMEI is only 6 decimal digits long. The rest of the IMEI identifies maker and model, possibly a software version number, and a checksum. Those parts are easily determined in typical attack scenarios. Not to mention that IMEI's aren't treated as particularly confidential anyway.
Basing anything cryptographic on the IMEI would be a really bad idea.
