Okay, finally I have decided to put my fingers down and code an SMS and Call blocker. Let me know if you guys are interested and what features you would like for version 1.

Here's what I am planning to do:

1. One app for SMS and Call block.
2. Block calls and SMS based on whether they are from your contacts
3. Black lists and white lists with wild card (*) for example do something like (+1*) to block all calls from US

Meanwhile, how about a good name for it? Any ideas
