I would have thought that a firmware update via Kies would preserve user data, contacts, apps I paid for from the market, phone settings etc. But after going from I9000DXJF4 to I9000DXJG4 using that appalling excuse for software (Kies) I have a completely empty device with just stock standard apps. No warnings to click through about wiping data, no strange error messages on the device. Is this normal? If so I might as well put my SIM card back in my iPhone until there is a consensus build of Froyo out for the Galaxy S as re-downloading and resynching everything each time is a right pain in the bum.
