Sprint's Touch: Overnight freezing, and my options

[exi]

My Touch has been freezing on me overnight for the past couple of months. It doesn't always do it, but it does do it enough to be a cause for concern. The phone becomes numb to any input and requires a soft reset.

I've tried hard resets. I've checked to see if it's software compatibility. I've flashed to the recently released 6.1 ROM as it appears on HTC's website. Nothing seems to stave it off.

So yeah, that's definitely unacceptable. I've emailed tech support at Sprint, but in lieu of their response, what sort of options might I have out of all this? Does it become an insurance claim, or do they tend to be liberal with providing replacement devices for seemingly defective ones, or will they allow a switch to another product entirely?

Thanks.
