Known Verizon Issue with cracked outer casing

[Amiroquai]

Crap, I just ordered ZAGG's IS for the xv6900 I'm about to buy today or tomorrow.
I'd hate to have to keep taking it off and sending it back for replacements everytime the shell on this phone cracks on me and I have to send it back for a replacement.
And I would not want to replace the housing on it myself either (at least for the first year) as I wouldn't want to void the warranty.

I'm very anal about my gear and I also got a silicone case to go with the IS, but what good would those do if the cracks don't necessarily get caused by dropping the device. and I know I couldn't live a crack on it no matter how well the phone was still protected.

I sure hope that it's just the vibrating feature that causes it so I can just turn it off (not too pleased about it either).

I wonder how common this problem really is and why the hell hasn't Verizon done anything about it when it's been like 7 months already.
