So a while ago my blackberry flip phone was dropped in a pool and the indicator was pink and the indicator in the battery was pink too. I couldn't get a new one from T-mobile so I just left the thing in my room for a couple of months now, but I feel like I'd like to use it again. It works fine, but only works for a very short period of time (2-3 hours) and I have to constantly charge it. Is there something I can do to fix it?
