Program should catch incoming/outgoing phone call events and start recording audio streams into memory or file.
Phone call should not be interfered with this new functionality.

This is not yet another iPhone application. This functionality is not possible to make with standard Apple SDK.
It requires solid knowledge of iOS architecture and ARM code disassembling.

Candidate requirements:
- Objective C programing 1-2 years
- Reverse engineering of ARM code
- iPhone jailbreak, cydia applications
- Private iOS API
- Experience in Free BSD kernel development
- Experience with IDA Pro disassembler or similar
- arm assembler, ?
- gdb, gcc, make

It is clear that this program probably needs to be recompiled/reworked for each new FW release from Apple and we are taking this risk.
Initial application should be written for iPhone 4 FW 4.1 or higher or for iPhone 3GS FW 4.1 or higher
