I plugged my 9900 into my PB charger (as I always do, when at home). Busy doing things around the my place and maybe a 1/2 hour later check my phone. Phone was plugged in, but my device was not charging. Woke the phone up and had the following error msg on my screen;

"The charging source connected to your Blackberry device cannot charge your battery"

I unplugged the charger and tried a direct USB to my laptop, it worked. I plugged in the PB charger again, same error. Soft reset, reconnected, no problems. Only had that error happen to my 9900, charging off the PB charger. I haven't had a repeat of the error.

Still think it's a bug.
