I work for a third party Sprint store and I went to the corporate sprint store in Chattanooga because of a problem with my Sanyo 8200. My phone would all the sudden get really hot without use or being on analog. It went through test and they said that it passed, but didn't know what. So they said that they wanted to give me another phone, but didn't have a sano 8200, so they ordered me a Sanyo VM 4500. I walked out of the store almost with my mouth open. So complements to Sprint
