If you’ve ever tried to dial a number such as 1-800-COMCAST from your BlackBerry device and ran into problems, you are not alone.  The keys on a BlackBerry QWERTY keyboard are not like those on a regular phone that automatically display the corresponding numbers for each letter.  Thankfully, there is a fast, simple, and best of all free solution for dialing numbers that contain letters without the need for any additional applications.  Simply start dialing the number as usual usually and when you come to the letters, hold the “alt” key while pressing each letter. Voila!
