Hardware and software setup for accessing and monitoring text messages on a phone connection

What hardware/software do I need to setup a machine that monitors incoming text ("SMS") messages 开发者_运维技巧on a phone connection? The software needs to be able to read the message, copy it to a database and then delete it.

Three ideas:

• Use google voice instead of a cell phone, and your received SMS will arrive as email

• Obtain a cheap phone that features a serial port on the headset connection and can use AT commands (AT+CMGR or something like that) to receive SMS, connect this to a computer's serial port using a cable with level translation

• Use an Android phone and write an application which does this.
