The developer of BlackBook, MBLware, Let me know about their application that gives you a secret contact list on your BlackBerry. It is only accessible by entering in a custom key combination on the keypad. The cool part is that it ties into the call and email and lets you view them with the right contact information through the application. It does not work as well with SMS due to API limitations but there is a workaround.
- Fully editable information fields keep your contacts up-to-date.
- User defined filtering for incoming and outgoing calls, sms, pin, and email conversations.
- Customizable caller-id names for incoming calls.
- Import and export the BlackBook contact list fast, and efficiently.
The app is currently going for $3.99 in the store which is pretty decent for such a application. It only works with OS 4.5+ devices so keep that in mind. The app has a few caveats that you should read up on in the FAQ if you are considering using the application.
Thanks DavidB, Tashanna, & KPatel for also sending this one in via BlackBerryCool!
