There is an article at ARS TECHNICA that can provide more info on determining exactly the iPhone model you have. It involves using sysctlbyname system call and considering the following information:

• iPhone1,1 (for the first gen iPhone)
• iPhone1,2 (for the 3G model)
• iPhone2,1 (for the 3GS model)
• iPod1,1 (first gen iPod touch)
• iPod2,1 (second gen iPod touch)
