You could also try taking the SIM out and putting it back again. This sometimes prompts the device to pull the settings down. You should see a notificatiion that you need to tap to install them. If all else fails, it may be necessary to do a factory reset.
If you're having problems with Kies, there are other ways of backing up. I prefer the file-by-file method anyway and proprietary formats have a horrid tendency to become suddenly incompatible.
Your contacts and calendar should be sync'd with Google anyway. You can copy photos, music etc by using a cable to connect to a pc. Make sure you tell that to view the phone as mass storage so that you can treat it as an external driive. If you want to keep SMS and call logs, there are apps that will hande that, but you'll need one that can use internal storage or and sd card if you have no data access due to the APN problem. Copy the resulting file once it's been created. When you reset, it's a good idea to remove the sd card if you have one as the process sometimes erases them.
