Phone Assistant version 1.4 is a great app that runs in the background and adds functionality to your BlackBerry that should be native with the device.
Phone Assistant enables you to quickly add contacts to your address book on the go. Once the conversation is ended, you will be prompted to add the contact only for new contacts if does not exist in the address book.
The existing functionality in the BlackBerry devices to add phone number to the address book only adds to the default “Work” category and in case you want to change that, the only way to go about it is to copy/paste. Phone Assistant will enable you to add the contacts in a quick and efficient way immediately without having to remember to add your important contacts later.
