Your phone will not be sticky, I peeled mine off
Usually, on any current cell phone, you can shut off the power of the phone, and then and take the back off, and then take the battery out, and then blow on the battery. That usually takes off all of the dust from the battery. After blowing on the battery, place it back in the phone, put the back on the phone, and then turn the phone back on. That usually works.....it works on my chocolate touch so good luck!
First of all try to switch it off and on. If it first method get fails then take out the battery and put it back and again Switch on the cell phone . If that method also not work then give to the cell phone store.
If the phone asks you to do it just click "reboot" otherwise, remove the cover from the back and take the battery out for 10secs put the battery back in the phone and wait for the red LED on the front of the phone to turn off and then start your BlackBerry back up again which will take at least 10mins.
Take off the back cover of your phone, and take out the battery. The battery should say what type it is.
