Blacklist in CyanogenMod

If you are running CyanogenMod on your Android device, and are surprised that some people seem to not be able to call you (half a ring, then hangup), you probably accidentally blacklisted that user.

My hope was that there was some simple method to clear this blacklist (which essentially "killfile"s phone numbers).  Either I misunderstood the user interface, or there was something desperately broken, but I could not figure out a way to clear the blacklist.  So I went digging in the source (yeah for open source!).

Turns out there is a file called blacklist.dat that stores these numbers, so here's my brute force solution for clearing the phone black list:

1. open terminal
2. su
3. rm /data/data/com.android.phone/files/blacklist.dat
4. reboot

Reboot is required.  Do it now.

And now, your wife is able to call you again, contributing to marital harmony FTW.

PS- no, I didn't tell you that you need a rooted phone, since you don't have this issue unless your phone is rooted.
