I flashed my Nexus 4 with Ubuntu Touch official 13.10 release. I wanted to flash it back to android and test the functionality on some things in android to make sure my phone hardware isn't a problem and then flash back to Ubuntu Touch. I've added a few dozen contacts already though so I'm wondering how I can back those up in some way that I don't have to manually add them again when I put Ubuntu Touch back on the phone.

I've searched online and seen this code for syncing contacts from Google:

```
adb shell sudo -u phablet -i syncevolution --configure --sync-property "username=email@gmail.com" --sync-property "password=XXXXXXX" Google_Contacts

```

and this code for downloading them from google address book:

```
adb shell sudo -u phablet -i syncevolution --sync one-way-from-server Google_Contacts addressbook

```

I was thinking maybe something like:

```
adb shell sudo -u phablet -i syncevolution --sync one-way-to-server Google_Contacts addressbook

```

might send the contacts from my Ubuntu phone to the google address book and then use the one-way-from-server code when I reinstall.

Would this be correct? Thanks.
