One thing that has always bothered me was receiving a call from a friend that was not from the number I had stored for them, whether it was an alternate, or secondary number, and trying to add that to their existing contact card was quite a pain. Luckily, gone are the days of writing it down to edit the contact from another screen, or copying and pasting to add it, instead meet ATEC, or Add to Existing Contact. The folks at MRythm Technologies must have also felt our pain, and that is what inspired them to make the experience easier for all BlackBerry users, and for that we are very thankful.
The process is quite simple, after receiving a phone call from a number you wish to add, press the menu button then select Add to Existing Contact, and from there you can replace the old number you have stored, or add it in addition, and you can select what type of number it is as well, be it cell phone, work, home, etc. Just like that you have added an additional phone number to a contact of your address book, without ever having to leave your phone application. The application is available for $2.49, which is a small price to pay for the added convenience that this brings.
