Only if they called your number blocked

When you Block Caller on iPhone, does it completely block them or do they show up as Unknown? I routinely "Block Caller" telemarketers, so does using the iPhone "Block Caller" option block all calls, or will the calls still come through and just show up as "Unknown"? I've received a lot of "Unknown" phone calls lately, so that's what I was attributing it to.
What's the difference between an 'unkown' caller and 'no caller ID'? This unknown number keeps ringing me, and i thought if someone blocked their numbers (on iphones) it comes up as no caller ID so i'm not sure if it is still a blocked number or a number that can't come trhough. But when i answer nobody speaks and they've rang one of my friends so its not a scam phone call also they don't speak at all so if it was a company of some sort they must of spoken so its probably a prank call but i wanna know the difference to make sure.
Is there a Iphone app that lets you block your caller ID? I have the iPhone through straight talk and i wanted to download an app to block my caller ID when i call people. Since i'm with straight talk, using my carriers block service isn't available since straight talk doesn't offer that. Any suggestions?
Is tbere any major différence between thé iPhone 6 and the 6s? Whooppeee is Xmas again and my daughter wants new 2nd hand) iPhone… 2 years ago almost bought her 5 before i réaliséd that it was 5s she wanted ( cos thé 5 sucks?) And I don't want to screw up this year…
