Why can't I add or edit contacts on my new iPhone 4?

On my new iPhone 4, I can add a new contact after talking to them (Add as new contact) but I cannot otherwise add new contacts, or edit existing ones.

It looks like a bug. Is there a way to work around it, or do I have to wait for Apple to fix their issue? The phone is not jailbroken.

You can use the Contacts application provided in the iPhone 4, and create/edit contacts in there.

What's preventing you from doing so?

The ability to add and edit contacts from the phone app is still available. I tested this just now on mine.

I had the exact same problem. Go to settings, then iCloud, go to the 'contacts' switch and set it to 'on' and it will fix your problem immediately.

It seems that the problem occurs when adding contacts to these phones after updating to IOS 5 (the + sign on the corner right is missing). IOS 5 added iCloud and if your contacts are not turned ON from the iCloud settings, you won't be able to add, edit or delete contacts.

The Fix: turn ON your iCloud contacts settings from Settings > iCloud and you should see your + sign on the corner back again.

just go to settings > Mail, Contacts, Calendars > if there is a accont (hotmail, g mail etc.) just delete the account and then automatically you can start adding contacts
