Help; ALL my calls come in under 'Unknown'

[leighedwards]

Hi, I recently switched to an Iphone 4. When one of my contacts ( Or anyone for that matter) calls me, it ALWAYS says 'Unknown'. Which is annoying because usually it's someone I have as a contact, but I never would know because it won't tell me. I have caller ID, but still it only says 'Unknown'.
It's very, very annoying and I hope someone on here can help me figure out why it does that.

(also, i have all my contacts numbers written in correctly, but it still happens)
Help mee.

It sounds like your caller ID isn't working. I'd call your carrier and have them check. Also you may want to restart your phone or even do a restore.
