Need a little help with some modifications

[blackhex666]

I want to modify a cellphone into a aduio bug.I searched around and i didn`t find to much info about the subject.I thought about disambling a old Nokia or somthing like that and removing the speakers,lcd,and everything that is not necesary.But i want to make it a little smaller.I want to connect the bug to the powersource of a optical mouse or somthing like that or inside my laptop

Instead of disassembling a phone, go for ready made GSM modules. They should start from around $40 USD (and can go as high as a smart phone cost ) Most modules are designed for machine to machine communication, but there are many available with voice capability (though u may need to add audio subsystem mic, preamp etc) There is a website with the name google.com that can help you find more information on GSM modules.
