I cannot get my iPhone 3GS to backup to iCloud anymore. The last backup was three weeks ago, since then no attempt was successful. The error message is ''There as a problem completing the backup. Please try again later.'' I have tried deleting my account and signing in with another. Then attempting to make a backup, which failed sadly. I have deleted my current backup. I restored my iPhone with iTunes. I'm at a loss. Every other topic I found regarding this is month's old. Or has no fix that works for me. My data does get synced with iCloud, because my Mac does get the agenda/notes/contacts changes. Is there anyone who has a suggestion on how to get this working again?
