Step 1- Buy an iPhone/BlackBerry (because in The Great Game he has a blackberry and in the Reichinball Falls he has an iPhone).
Step 2- Your text ringtone must be the one you'll find at http://www.youtube.com/watch?v=Dr8HDRvlKog
Step 3-Always text (if possible).
Step 4- If sign your texts, the correct signature is:SH.
