Trouble with unblocked contacts
I recently unblocked one of my contact, however the number is erased from my recent calls and contacts and I deleted the IMessages before I blocked that person. How can I retrieve that number?

You'll need to get it from wherever you got it in the first place. If the number is included in a back up you have of your phone, you can restore the phone from the back up. However, you'll lose everything you have added to the phone since that back up,
