How do you block iPhone number when calling out?
What you do is dial *67 in front of the number you want to call. If you ever prank call someone with this strategy, it will come up as "restricted" on the other line's screen. Hope the person you're prank calling doesn't know it was you! :)
If you mean to block them sending texts to you or calling you, you would have to call up your Network Operator as there is no inbuilt blacklist on the iPhone 4. There is a way if you have your iPhone jailbroken which would be to download iBlacklist but it does cost to download it and I don't recommend jailbreaking.
To block a specific phone number from texting you on a PagePlus phone, you can have the provider disable SMS on your phone. There is currently no way that you can block a specific number from calling you on a PagePlus phone, but if you report the unwanted calls to the FCC, you may find that the calls stop.

To block a person from calling or texting you is to go on the Internet and go on the website of the phone company that you have ( T.Moble,Verison,Sprint,etc.) and when you got your phone you should of got a account so type that in on the Internet and you can just go to account settings and click block and type the number in.
You are not able to block any phone number manually from any cell phone. You could call your cell phone carrier and ask them to block the phone number for you. You can also put the contact you wish to ignore in a ignore list where your phone will not ring or vibrate when they try to call or text you.
