How can I store text messages and list them using GSM module?

i'm trying make mobile phone using gsm module "sim900a", able make calls , send text messages want make list of messages sent mobile gsm , able read them. should add code this?

this link tutorial have followed more info:
http://www.instructables.com/id/gsm-sim900a-with-arduino/

code: [select]

/*this tutorial used gsm sim900a mini v3.9.2
 
  connect 5vt d9 , 5vr d10
  feed gsm sim900a arduino's 5v

  code idayu sabri - mybotic

you've got 2 choices.
1. store message on arduino @ time of sending.
2. attempt find @ command gsm module gives access stored data.
