I heard you can block calls/numbers with ios6

If so, how??????

You heard wrong.
The only thing close to this is Do Not Disturb mode, but that won't block calls.

You can't! What you can do though is use "Do Not Disturb" feature to silence your phone and only have your phone notify you when you receive calls from people you want. You will still receive calls from others.

if the same number calls, create a contact with that number and use a ring tone of silent. I use it for repeated calls that I can't block - the scammers who robocall. I have contacts named "do not answer 1" "do not answer 2". it's easy to find a ring tone of silence.

You can do that on Sprint, but I have not seen it on the iPhone 4S or 5.

You can block numbers through your provider regardless of phone or os.

Sad that it's yet, another feature that many dumb phones had years ago, but the iPhone still doesn't have.

Silent ringtones are fine and dandy, but they'll still vibrate or interrupt whatever you're doing if you're using it.

A lot of carriers offer these kind of features these days, so that might be one way to go.

Would be nice if there was at least an app for that, so to say...and there might be one, like Mr. Number or something similar perhaps (haven't really looked too deeply into it before).

You can also set a vibration of "None" on a per-contact basis.

One of the features I miss the most about my Android phone: the option under a contact to "send to voicemail"

It would be really nice to have this on my iPhone...
