Via recovery zonder backup terug te zetten lukte het dus wel
Ik heb inmiddels dit gevonden :

Solved! I have completely fixed this problem without losing any data (not that i've noticed yet anyway).
First, let me summarize the problem and briefly address the known solutions. There are multiple issues people are having with the update that -HAVE NOTHING TO DO WITH OUR PROBLEM-. Some people had theirs in airplane mode which apparently gives them a "no sim card" after update. not our problem. Some people can reset settings not our problem.
Our problem is corrupt APN settings after an upgrade, which can be worked around by installing mobileconfig updates or using the "iPhone Configuration Utility" to temporarily overwrite our APN settings. This is a temp fix that only makes 3g work, no MMS or Visual Voicemail.
We know that completely restoring the phone and setting it up as new resolves the problem. A lot of us are unable to restore any backups without re-introducing the bug. A lot of us do not want to lose our app data so setting up as new phone is out of the question. Some people have figured out how to set up as new phone and import SMS messages from corrupt backup to new backup. This is a good solution if SMS is the only thing you want…However, some of us want ALL our app data.
Now for the solution! First, go in to settings on your phone and uninstall any custom profile you may have installed to temporarily fix the APN.
Now, perform a full backup of your phone (you may want to delete your previous backups or move them out of the directory so that you're not confused with multiple backup files in your backup directory.
Go to your backup directory ~/Library/Application\ Support/MobileSync/Backup/random-backup-name-here/ and delete this file 8218978e4ab0a48035bb92653145a6be872ea858
That file contains our corrupted APN information.
Now RESTORE YOUR PHONE and restore the backup. It will fully restore and then give you an error, ignore the error, it worked. Sync your phone to get all your apps back. 3g works, visual voicemail works, mms works, and i have ALL of my app data! all my contacts, all my photos, all my sms messages! BAM! I RULE!
If for some reason you don't have that file in your backup directory (i have no idea, maybe they are named differently with different backups) you can find it by entering the backup directory in the terminal and running the following
