Cell phones like Nokia are redundant, and it has got a 1.8Ghz transmitter, and an LCD display too with ucontrollers and reciever too...why dont some one who is free try to reprogram these to build a GPR...

Joking aside, this is a good idea, certainly some of the bits could be used to do what you suggest. -
WOW - Who can reprogram Nokia...
You can not use this 1.8/0.9Ghz transmitter - you need stop/start transmitter very very fast....
From Nokia you can use only display...Comment

I used to work for Nokia designing base stations, and mobiles, so I think this is actually possible.
Considering a cell-phone can frequency hop at a quite a fast rate, and can also control it's power output I don't think its a great leap of re-design to make it do something different. You would need access to the layer one software or possibly a re-write of this to custom control the hardware, but it IS possible, but would require a very good software Engineer.
Take a look at the Nokia N95 mobile phone, easily 50 TIMES more processor power than ANY metal detector on the market today and yet it can be bought for around $300 and has a battery life measured in days, not hours. All this industry needs is ONE good designer with a FULL appreciation of what can be done with modern DSP, and metal detecting as we know it will change forever. FACT.Comment

N95 is BB5 platform and you have not access to boot mode for Texas Instrument processors(RAP3G and company) - you can not upload your software to phone....
In Java and Simbian - you have not access to TX..RX API...
About this processor - good is for GUI - Graphic User Interface, but for metal detector.........Comment

There are softwares available in india to hack these systems like mobiles etc, better to get a source code rather than reverse compiling them, its very easy to program the micro in c if one knows the circuit diagram along with data sheets. Sean Goddrad can do this I think or any one access to schematic of mobile can takeup this project, we can start and stop the transmitter instantly by looking into the data sheet of the Tx stage, or add an extra gating for Tx...Comment

You are very brave to maintain this for Nokia BB5 platform...
