Safe to assune that this does not have the Samsung backup utility included for contacts? Am running Evil and am thinking of giving this a shot as my battery life is not great.
If you are talking about the setup/backup thing why does anyone use that? I use Titanium Backup from the market, and just to be safe i go to settings-> Privacy-> and check the settings for back up my data and automatic restore. Then all you need to do is go back one from there and up one to accounts and sync-> tap the google logo with the green sync icon, to make it stop. After the sync icon turns grey, tap it again to get sync going again. The last part probably isn't necessary but if I am gonna back it up I might as well make sure it is actually doing it.
Oh and sorry guys but i had to jump ship cause jt1134's Cyanogen GB rocks!! dancedroid and go sms pro is free in market and fixes mms problem, I just uninstalled the Sammy sms anyway, cause i think its crap.
