... I'm excited! The Betriebssysthem BlackBerry is stable and without jerking. It can be quite simple, but very individually set. The device is indeed made of plastic, the processing is, as usual, by BB, Erstklassik! Nothing creaks, the control buttons are stuck and have a pleasant pressure point, and the rubber backing gives a secure fit; especially for larger hands. Send and receive power, the voice quality (I use the power of O2) are even with me on "the country" outstanding! I would buy this product again.
