They are still replacing it.
My 6700 was constantly freezing so I turned it into the Sprint store. I came back an hour later and was told they couldn't fix the 6700, so they are giving me a NEW 6800!!!
Pretty cool, just have to pay $35 for the replacement or something.
When I purchased my 6700, I knew sometime in the future I was going to get a 6800. So I bought a 2gb MicroSD and got a MiniSD adapter. So now I dont have to buy another memory card
