I bought a new blackberry bold unlocked on amazon and took it to Brazil. On the first days it was working well, but then one day suddenly, when I still had 3 bars of battery, appeared a message saying "The battery has drained. Device shutting down". Then I tried taking out the battery but it didn't work. When I got home I connected it on the charger and the battery was red with the radio turned off. Now, every day this message appears. What should I do??????
