Hello as the subject,
is there any 3rd party software which can do the job ?
(update existing contact number from call log), i think that blackberry lack of this ability.

it only can add to address book (which it create new contact) or copy the number and i have to edited the address book manually, so can anyone help me to pointing out any software (both paid or free) which can do the job done ?

You have found the two options... I am not aware of another more automated method.
