Arduino cellphone control

I need an arduino device, that will be able to use a cheap cell phones keypad (transistors will be soldered to the phones keypad in order to simulate key presses). The device needs to reference 2 separate text files with data to know what to input through the keypad and create a third one as a log.

Here comes the hard part. The cell phones speaker leads will need to be used as either analog or digital inputs on the arduino itself or using a shield , in order to analyze sound. There will be 2 types of different sounds and the spectrum analyzer simply needs to tell which one of the two it is. No voice recognition necessary. Bid/message for further details.

(In a nutshell the device will replace a person who has to manually input data through a cellphone)

Have a lot experience with similar projects. Does it have to be arduino? Maybe TI or Microchip have some popular and better options for this task, but basically it's very similar. Anyway... I'm very interested!
