Just curious, as I am looking to purchase one.
I upgraded from an i530 to an i880 recently, which turned out being a mistake. I tend to beat my phones up (not intentionally, it just happens), because I'm a farmer and also work at a steel mill. My i880's keypad quit working after only two months of use, and the sound would also stop/start working randomly. Because of this, I've decided to stick with rugged phones.
