As if you needed more reasons to jailbreak....... and it works with iPhone4 on iOs 4.0.1. It's $12 with a trial period. Paid for itself with the one time it allowed me to sleep in today.
The program just works wonders for me - it blocked this telemarketer that's been calling for weeks, that is until I installed this program. They would have woken me up, but when I checked my phone later in the morning, I saw the little phone icon in the statusbar letting me know they had been blocked. Their call doesn't even show up in my recent/missed history, although it does appear in the iBlacklist history log. I have them set to "busy signal", which in my tests actually doesn't even connect the person's call. It immediately disconnects them, similar to when your phone has no service and drops the call. Calling from a landline may actually give them a busy signal though. The telemarketer didn't even get the satisfaction of knowing the phone rang and can't even leave a voicemail.
You can also set it to instantly go to voicemail, instantly answer, or ignore (which lets it ring on their side (not on your side) - not sure if this eventually goes to voicemail - as I've not tested)
It even has wildcard blocking, meaning you can block 222-555-xxxx and nobody from that wildcard will be able to reach you - as telemarketers do have a string of numbers they can call from. To do the wildcard block, just enter a number in the format: 222555*
You can also setup blocks for restricted/blocked calls - to answer/busysignal/ignore/voicemail them. This also works with mms/sms. You can block mms/sms from certain users; even allows you to auto-reply with a custom message if you want.
I used this in the past on my 3G/3GS and had some trouble where it would block users not on my list. I was still able to see the blocked calls/sms, so it wasn't too bad. But their latest version hasn't let me down.
