[+Rep] iPhone4 - How to block specific phone numbers?

I keep getting these annoying texts from a guy I gave my number to ages ago. I was wondering if there is a way to block specific numbers on the iPhone 4? +Rep for good answers :)

I very much doubt you can, I believe it's done through your network provider. Type into Google "Blocking numbers x"

x = your network provider

I don't believe that this is possible

Contact your network.

You can do this on Android...

I tried to do this before, apprently you gotta jail break it then down load this app, I didn't want to do this to my phone and I doubt you will to mark :) Other than that I'd contact your network.

surely theres an app to filter it, on android you can get tons of apps that do this.

I would ring up your mobile provider up and explain the situation. They should be able to block the number.

jailbreak your iphone and download iblacklist from cydia.

Thanks everyone! Thread closed and giving rep now :)
