Crashed, never worked, screwed up my iPhone – Jima Caller ID Review

The app failed to block even incoming junk calls in its own database. The huge database has corrupted the Contacts app on my iPhone and also prevents me from completing my iCloud backup. I have spent much time with Apple Care on this issue and still haven't resolved it. This app is a disaster for me. Terrible experience.
