Do you have another calendar account on the iPhone 4. Settings>Mail, Contacts, Calendars, Accounts?
You may have calendar sinc turned on in two different places, iCloud and as described above. I don't have an explanation for the half hour off.

Can't help with the thirty minute difference other than that it may be a bad setting in the date/time portion. However, if you sync to the cloud and also to a mac be sure not to sync the same calendars with the cloud that you sync with the mac. I found that checking the box in the info portion of itunes that says calendars can cause dupes. What was happening was, the mac and phone sync to the cloud, then the phone syncs with the mac, and voila, dupes.

iCloud is the only Calendar, and it is correct on icloud.com and on my 4s.
iTunes sync iCal is unchecked.
The only Calendar(s) that are used on this 4 is sourced from iCloud.
Good troubleshooting help, thank you, I had already covered that, though.
Oh and I might add that scheduled (repeating) events that were deleted over a year ago, appear on this icloud calendar, too (on the iphone 4). So does a person's birthday, but 5 times on the same calendar! Mutliple occurances of that.

Hi John7, I'm having the same issues with my iPhone 4 and iCloud calendars--duplicates and quadruple/quintuplet duplications on repeating events. Apple Store Geniuses had me try wiping and restarting my phone like it was a brand new phone, but that didn't solve the problem. I guess I have to manually delete the dups/repeats (but my calendars go back to 2006--ugh!).
