What's this weird symbol on my iPhone?

I was looking through the contacts on my iPhone 4, when I noticed a weird symbol next to one of them. It looks like a silhouette of a person, and the name and the silhouette are hilighted in blue. This is the first time I have ever seen this, and out of all my contacts, only this one person's name has this. Does anyone know what this means?

How to get deleted text back on my iphone?

I accidently deleted a message with my friend who i've been texting for a while now and we have so much funny moments and good memories on the texts, and i always loved to read over our old texts but i'm so sad now that i accidently deleted it! Is there anyway that i can get it back? Our texts were filled with memories! :'(
i have the iphone 4s, by " deleted ", i mean when you go on your messages, and there are lists of messages from different people, and i swiped on the name and then a delete sign comes up and clicke delete. But not " clear message " which i found that you can do to your message and " clear all " is
the same as " delete " but i don't know the difference but whatever. I'm desprate to get my texts back?

Unable to activate my restored iphone?

My dad gave me his old iPhone 4 after restoring it to its factory settings.
It comes up with an error message that states

"Unable to complete your activation
This device is not registered as part of the iPhone Developer Program.
If you are a member of the program, please register your device in the iPhone Developer Program Portal."

I've tried wiping the phone again and putting it in recovery mode.
Also tried following the link to the developer portal thing but that didn't help, whether or not I did it right.

Any help?

My iphone 4 is being stupid?

Alright, so when I got the iOS 6 update, it wouldn't let me send, only receive, but then I fixed it by just continuously restarting, hard reset, and resetting network settings several times.
Now it's been 3 days since then and now my phone won't send OR receive messages. (It says it sends but noone actually receives it)
Has this happened to anyone? Can anyone help? Please?
