I got a Blackberry Key 2 from a reputable source that was supposed to be tested for functionality. In setting up and configuring the device, it asked me to type in for a WiFi connection the passphrase. When you press keys on keyboard, nothing gets typed. What do you suppose is the problem? Is there a setting that's going to work that I can access at this stage that will let this work or is a cable unplugged that needs repair.
