The newest app from Twinkler Software (makers of AddOnIs) AddContactX, lets you add a contact quickly after ending a phone call. This can come in handy for many business and personal situations, and now couldn't be easier. After ending an incoming or outgoing call, AddContactX will prompt you to add the contact information to you address book for a new or exisiting contact. You may choose a new contact and select the field (work, home or mobile) for the number, or update an existing contact. After the number is saved you will never be prompted to add that number again. You may also choose to ignore a number, in which case it will be ignored in the future as well. AddContactX is available in the CrackBerry App Store for $2.39 (20% off the regular $2.99 tag).
