On my Droid with firmware 2.01, I just restored my Contacts list, (after I had mistakenly deleted two contacts), using the latest 2.2 version of MyBackup Pro by Rerware, from the backup file on the SD card.
I had over 900 contacts. Now after restart, the Contacts List shows fewer than 100 contacts!
Tried this several times, even did a reset by removing battery. Same result. I now only have a few contacts!
And MyBackup Pro was supposed to be the highest rated most reliable backup APP for the Droid.
