I just bought a new Blackberry Z10 Holster two hours ago. It's really nice except for one problem. It has powered down the Z10 three times? Like an moron, I tossed the box it came in at the mall. So I don't recall if it came with any special instructions? Has this happened to anyone? Also, does anyone have any suggestions? P.S. I'm new to Crackberry and I want to thank Kevin and his team for making the launch enjoyable.
