weard!!
You wont believe me but i had the same problem, my iphone 3g tuned off whenever he wanted and began to do it more often, happened so many times and i tryed many things that I resigned the phone was dying, until i remove the Rubber Case. May sound strange, but from that moment the phone has performed perfectly, I have no problems at all even though it occurred to me for several months and often. ****ING WEARD.
