Hi there, I've just wasted the entire afternoon trying to figure out how to backup all of the stuff on my Samsung Galaxy Ace to my PC. A google search came up with Kies, which I successfully downloaded and installed, but whenever I try to connect my phone (it does read it correctly as GT-S5839i), I get a message saying "unable to connect to GT-S5829i. Failed to retrieve driver information". Tried troubleshoot tool. Also tells me it did its thing successfully, but it doesn't change anything. Restarting PC didn't do the trick, either. Very frustrating. Please help, thanks! (And no, I don't want to root my phone or do anything fancy. Just want to know that if my phone dies on me, I've got somewhere to go to to restore my contacts, sms etc. Anybody know how to do that? Thanks!
