How can I block incoming calls on my iPhone?

I hate that iPhone doesn't have this app. I'm pregnant and split with my partner who is now seeing someone else. I'm happy for him but don't want to see his missed calls and messages. It breaks my heart and tears me up inside everytime he calls. I just want to block him till I can move on and my phone provider doesnt support blocking. How do I jailbreak my iPhone 4s? I really can't handle him calling atm and he calls every day so I won't let him go.

I agree.. I want my iPhone to answer then hang up on blocked calls. By doing this my phone will never ring/vibrate and/or leave a message. I bought CALL CONTROL years ago (1x fee) on my BB now i use it on my Droid.
Call Control does exactly that.. answers then hangs up on blocked numbers. My BB/Droid were both on ATT so i know it has nothing to do with ATT. It's Apple.

BTW.. I only know about Blocked calls as they do still appear in recent calls. That's ok because I just don't want the phone to ring and/or give these blocked callers to the opportunity to leave a message.

I just create a name in my contacts list called "Spam" add any number to it which I don't want to answer (eg telemarketing numbers) and then don't answer those calls.

Hi! I have iphone 4, ios 4.... May concern is how do i download the old version of facebook without upgrading my iphone to version ios5? Lastweek i deleted my facebook for some reason....but now im trying to download again but unforetunately i cant able to download because now the facebook is upgraded already. Please somebody help me!

While it is true you cannot block a number without paying AT&T or you carrier for that service and many like myself do not wish to jailbreak their phones there is another more fun option. AT&T offer conditional call forwarding. I set mine to forward the call if I do not answer which means I can pick up the phone and talk to my friends/contacts whenever I want or pick up from a legitimate call if the caller I'd number is one I wish to chance, but here's the fun part. Call forward the call back to that annoying telemarketers number and melt down their phone exchange. The more they call the more their system is taxed and when enough people do this it collapses their system. If they don't get the hint rather quickly you can always forward it to a federal law enforcement agency who will quickly have words with them for you since its their number which will register as the offender.

I have a unique situation regarding blocking calls. My brother is in the hospital after an organ transplant. While he's stable, he still has problems. The issue causing me to block incoming calls, is that confused and not in reality. He doesn't know where he is, what he's doing there, what time it is, or anything.. Its like he has Alzheimer's. He is able to talk and make sense on a very elementary level. He's in Intensive Care Unit in a hospital, and he's very, very bored. He has a business, which is (was) his whole life. Until he comes out of this fog, he most certainly can't work. BUT HE WANTS TO. He wants his phone to contact his vendors and customers. I'm currently running the business and if he had full use of his phone, it would be disastrous for his business. I plan going to put the family's numbers for him to call out, but I need to find out how to prevent incoming calls. We call the nurse's station if we need or want to contact him. So there's no need for him to received calls. Any ideas - he has 167 contacts. I saw where ATT charges $5 a month (is this per caller?) PS, he's been in the ICU for six weeks, and there's been no change. His prognosis is indeterminate and not uncommon for very few patients with like symptoms. He could be in ICU for six months or more, no one can tell. I want to give him a phone for him to have very limited contact with the outside world, no incoming calls. Any ideas? Any help would be most appreciated.....

Hello, I really need help, I had to take away the iphone 5 from my 14 yo daughter as she is texting and calling some really unwanted friends of her, I would like to know if there is an app that would make the opposite than block, that is ALLOW ONLY CERTAIN NUMBERS INCOMING AND OUT GOING text msg and calls , I would put only my number and her mom's, so i can give her phone back . I know already how to block all the other apps, so i have no problem with the rest , but I need her to have her phone when she goes to bike or gym etc...any help will be really appreciated

regards

Not sure how old this FAQ is, but you can block callers on your iPhone running iOS 7. Click on the "i" beside the phone number in your Recent Call list > Scroll to the Bottom > Choose "Block This Caller"

If you have an IPhone 4s go to contacts select the person you are looking for, then scroll down and it says block this caller. FYI!!!!!!
