I've had my blackberry for two years now..
for the past couple months ive been having issues with charging my bb using the mini usb cable,
What happens is my phone has issues connecting to the power supply. I have to play with it a bit to get the lightning bolt to appear. Half the time the plugged-in icon appears and the battery will start to drain...
I've cleaned everything to my ability and still nothing.
I have to play with it for a good 25 minutes before i can set it down without losing the connection.
Any tips?
