I had titanium backup installed on my phone when i installed liberty , would that help me get my contacts back? I upgraded to pro version but still says only 1 app at a time . There are several files that pertain to contacts so are these not obtainable?
Best suggestion I have, is get the contacts sync'd into Google Contacts, and not have to worry about them if you ever change ROMs again. Most ROMs don't use BackUp Assistant (BUA), and Phone contacts seem to cause issues with AOSP (at least, some people have reported on Focused before)...
This might help:
Migrating contacts from "Phone" (BackUp Assistant), to Google Contacts
Import/Export from SD card is faster/easier. Just go into contacts, hit the menu key, then export to sd card. Then after you flash the ROM, just import from SD card and everything is back.
