Has a complete shutdown happen to you?

[operaghost]

Just bought my Sprint Q a month ago. I was playing the media player for about 1.5 hours and all the sudden the phone just shut off. I couldn't turn it back on. I don't think it was the battery, I didn't get a low battery message. When I plugged the phone charger in it still wouldn't turn back on. Finally I removed the battery and then put it back in and the phone did turn on after that. I am worried about this.

Any comments on this would be greatly appreciated!

Thanks.
