Blocking-Call and SMS running in the background, please help urgently .

[coolturkishboy]

Galaxy S bought the Samsung, but I can not use properly because I could not find a call blocking program.

Previously I was using Windows-based phone and i used magicall, the Nokia E72 i used MCleaner.And that programs was really great But I could not find an application running in this way as the android application.

That application need to be run on backround..i mean when somebody call who is blocked ..there must not show anything on the phone..and just run on backround..and also if that program forward the call to another number or rings but not shown....block features must be like that..

İf i dont find a comfortable block program i could not use my new phone ..

İ need really help..

Thanks..
