I am having the exact same problem! I have received a replacement phone in the mail and a new battery. The thing that I do not get is that I live in St. Louis and went to Indy this weekend and the phone did not reset one time the entire time I was there for three days... As soon as I got back to stl it reset like 4 times in 2 hours. I called today and they said that they were having problems with a tower in the area. I said for two months?... It has been doing this for two months now. I also have three other lines and one of them is also a htc inspire and they are having no problems. They reset the sim card and re registered me and it was all good for about 5 hours and it just reset again. Any ideas would be awesome.
