Jabra vbt2050 won't connect

Question

I bought a blackberry curve and a jabra vbt2050 bluetooth. The bluetooth paired and connected twice. Then I got a message that the bluetooth could not connect. I deleted it from my phone so I could try to re-pair the bluetooth. Now the bluetooth will not display a constant bluelight. It flashes a few times and then turns off. I have been charging it for days, but it doesn't seem to change anything. I cannot pair the device now.
