Tingali publicity lang jud para mahalin ang z1 sa waterproof nila na feature. I have a motorola defy ang have submerged it for quite a while and a lot of times (as far i can remember around 10 times). gibilin pa man gani sa sulod sa aquarium for pila ka mintues to take video but ok ra man, ako lang gi make sure everytime na i dip nako xa sa tubig i sure (double check) nakaseal ang ports (headphone jack and charger port). until now good running condition and is running on custom slim rom. so wala jud diay au ang sony. plus the price of 30K plus not worth.
