Can you block a number from calling or texting your iphone?

My friend is having trouble with someone texting and calling her. It's not a telemarketer, just an old friend who she doesn't want to hear from anymore. Is there anyway she can block him from calling and texting her iphone? Any help greatly appreciated.

What are some good iPhone 5 deals?

So, i have verizon wireless, and i'm very satisfied with my service. The only thing that i don't like about verizon is my phone. So I have decided that i want an iPhone 5.

Don't tell me that the iPhone 5 is overrated or not what you think it is, because I don't care what you say, I'm still going to get it.

If I do decide to just by it out of the blue, i will have to pay $649, for the unlocked phone. I only have $500 anyways. Knowing that Black Friday, Cyber Monday, and now "Brown Thursday" i KNOW there are going to be some deals for the iPhone 5.

The only problem with that is the fact that this is my first time shopping on black friday. So i have no idea how to find good deals.

Saying that, it would be EXTREMELY nice if you guys could give me some deals on an iPhone 5 on either "Brown Thursday", Black Friday, or Cyber Monday relatively close to $500, i do have parents, and their made out of money so i could get some help if it is a little over $500. One other thing to ask is that you don't give me a really sketchy website thats just going to scam me.

How to get rid of update sound?

I have a jailbroken iPhone 4s and if I go into my setting it says I have an update I need to install but I can't because it's jailbroken and it just says error. It makes an annoying ping sound about once every 20 min. If you could tell me how to install an update with a jailbreak that would be great, but if not I just need to know how to turn off that annoying sound!
