Apple iPhone 3G Software Unlock Needed

I'm looking for an experienced "iphone" programmer who knows iphone system very well and also had released a successful "unlocking" software before. The software (desktop application) should unlock the latest firmwares 1.1.x to 3G (8gb and 16gb models) and all other old versions without any problem with a simple process by just clicking a button. The software should unlock all networks including such as AT&T, UK o2, French Networks, German Networks etc. The software must fully unlock the Apple iPhone 3G firmware and older versions to work with any GSM Carrier SIM card. The iPhone is a quad-band cellphone however it is locked to specific major carriers such as AT&T, O2, etc. This will be a bigger project and I am offering up to $1000 USD to whoever can get this done. So far only hardware solutions are availble such as a "TubroSIM" but what I need is a software solution that can unlock a LOCKED iPhone and make it work with any GSM carrier. Developers for this project should have basic knowledge of communication boards, mobile phone firmware implementation and how all internal parts of a cellphone are structured and function. The iPhone has a sophisticated software structure build around the MAC OS. Please do ask me any questions you may have. Thanks, Bill
