The contacts in your Gmail account are very important, and is equally important to keep them updated and saved, but what happens when you delete by mistake, there is a way to recover with the new feature in Gmail that allows you to restore a deleted contact for 30 days after it is removed, if you spend more time then you can no longer recover.
To access this feature in the contacts section of Gmail, there is a menu called "More Actions"There must choose the option called"Restore contacts ..."And you'll leave a box like the one pictured above, with this going to restore all deleted contacts in recent days, you pick the time, but the bad news is that if you aggregate a new contact will delete as you return your database of contacts at the same state it was the day that you restore it.
This is one more reason to use Gmail instead of any other free email service.
