i have the curve 8520... it was working earlier today I changed my sim card so I put my phone shut off. After this when I switched on my hand set...... then I found a battery symbol with a red x and the phone is not booting OS. I am not sure what that means but my phone won't turn on and won't charge. I tried taking the battery out and now it turns on but the symbol is still there and the loading bar is on the screen and it won't change. I also took outmy sim card & memory card. Please help me...
