97 is a bit warm, but normal if you're charging AND using the phone at the same time. I was just in 4G LTE today (my area doesn't have it yet) and I noticed (after a lot of web browsing and speed tests, without charging) the back of the phone (around the battery) was a little warmer than usual. The HTC battery widget indicated it was 95F. Normally, it's more around room temperature (70's) or in the mid to upper eighties at the most when in 3G. It never did go above 95F and cooled back into the upper eighties and lower with less activity. Regardless, I never noticed any performance degradation while using the phone.
