LG Electronics introduces a new Black Label Series phone that follows the LG Chocolate and LG Shine and promises to be as successful or even more.

Update:
LG Secret LG-KF750 is official

LG only released photos and some highlights of the new Black Label handset. They did not even reveal the name of the new very thin looking slider style phone.
The new LG Black Label Series handset features a 5MP camera and a case design that utilizes materials such as carbon fiber and tempered glass.
My guess for the name of the new LG phone is LG Carbon - sounds good and highlights the carbon fiber in the case.

LG will fully launch the new LG Black Label Series handset on April 24th in Europe and the rest of the world.
See hi-res photos in the story's gallery.
