If any other phone uses PDQ libraries, then it should work with them too. Currently it has a provision of blocking only one number. Once I get time I will implement for more numbers to block and other features.

Note/Known bug:
After syncing the program, edit the number and then reset the phone. You need to edit before resetting the phone or before you receive any call.

If you forget to edit it before receiving any call (after restting the phone) phone will lock up and you need to perform a reset (soft).
