Hi,
I have a BlackBerry Pearl Flip (8220).
Now, as you may know, there is a compartment at the bottom of the battery cover, as you can see in this photo http://smslife.in/blog/wp-content/gallery/blackberry/blackberry-pearl-flip-8220_4.jpg, and there is a little lock(from what it looks like) in between the two things on the side that probably secures that in. Well on my BlackBerry that piece broke. I was just wondering if you guys know what to do, have any suggestions, or have any links for a website that supplies replacement pieces for this part.

Thanks
