Okay, I have recently (august) bought my gravity. Brand new. I took a shower with it on the counter about 3 ft away and some how water got into it. It was fine until today. Like this happened a month ago and it would just turn off and i taped the battery and it would be fine for a hr before turning off. But now it says insert SIM Card tonight i spent 1 hr re-positing the sim card. Any suggestions before i go into T-mobile?
