IMEI and Flash Lite Bug with Bluetooth

I recently have noticed a bug in my Flash Lite app, the Imei Number (Identification Number of Mobile Phone) won’t show sometime, first I thought about an error of my part, but the same application would sometimes work and some other time won’t.
Well it’s seems that when you got a Bluetooth link working, your Imei Number won’t be accessible.
I tested only on my device (N90) but i was wondering if anyone else did notice this bug or if it’s only related to N90, Symbian8.1a-Series60v2-FP3.
Anyway if you got this bug don’t look further, the only solution I found by now is to simply link off your Bluetooth and then “sans problème” the Imei will show ;)
