My 6 month old K800i died on me during the 2nd day of CNY. It just suddenly powered off and will never switch back on again. This K800i is my very first SE purchase after having used Nokia all this while. This is a very big disappointment from SE to me. I guess this K800i will be my 1 and only purchase of an SE phone. The phone is with the hp shop now. They're still trying to diagnose the problem. Sigh...
