iPhone sync using iTunes gets stuck on step 3 of 7 syncing calendars
I am getting stuck on step 3 of 7 when syncing my iPhone 4 using iTunes. I have had this happen before with iOS5 but it seemed to sort itself out after I deleted the backup from iTunes 10 > Preferences > Devices > iPhone backup and synced again a couple of times. I recently installed iOS6 and the sync problem has come up again. Apps and contacts seem to backup fine. I have tried deleting the backup and a reset (by holding the sleep & home buttons down) but I still don't seem to be able to get past step 3 of 7 sycning calendars. I noticed that a few users seem to have this problem from time to time. Any help would be greatly appreciated.
iMac (21.5-inch Mid 2010), Mac OS X (10.6.8), Also older Macs
