Can I Block Someone from Texting me on my iPhone 4?

When I finally got to college, I thought I was free from my horrible life, but now my mom keeps sending me evil, passive aggressive text messages. Is there any way I can block people from texting me without just throwing my phone in the toilet?

There's an app called iblock I believe. But there's not a way to block someone from the actually phone. That's the one thing that I don't like about iPhones

  • Is there any possible way to block a number from texting you on the iPhone? This guy I used to be friends with keeps texting me bad messages and it's creating problems with me and my boyfriend. Is there any way I can block this number from texting me? I have AT&T and I don't want to pay $4.99 a month for smart limits just to block one number. Is there an app or a feature on the iOS6?
  • If someone were to block my text now number would it block my normal number? I was teasing my girlfriend on my text now and she blocked me and I tired calling her and texting her on my normal number but she won't reply and it only run once and hung up. She has an iPhone, would it block my normal number if she blocked my text now number?
  • If I block other iPhone users from calling and texting me, will they know? I've got a 4S and was wondering if I blocked a couple people in my contacts with the same phones if they would know? What would happen if they called or texted me? Really need to know before I go ahead and do this, that way I don't get criticized for shunning them out of my life. I just can't deal with their annoying and ignorant texts anymore. Some friendships just don't last I guess and I'm too kindhearted to just tell them to downright quit texting me. Thoughts?
  • How to block your number when texting someone on iPhone 4? Someone texted my friend and was trying to act like me but I don't know who it was. They were using a pinger number so it wouldn't let me call them. I have an iPhone 4 and I want to text them without them knowing my number. How can I block it if I text them?
