When I first registered my Ace, I made up a random email account. I've now got a decent email account and have used it for my Tab 2. I want to sync the two and have to change the default account on the ace to use Google Calendar. Having searched the internet I think I'm resigned to having to reset my phone. So the questions are: If I reset, what do I lose. How do I backup the things I lose to restore to my new account name after the restart? I would not want to restart only to find I could not restore contacts, texts, pictures etc.
