"On the new IOS 6 soft wear it says that my i pod 4g can have suri"

That is not tue at all. It says the opposite. it clearly states:

"

Siri is available on these devices:

• iPhone 4S or later
• iPad 3rd generation or later
• iPad mini
• iPod touch (5th generation)"

and

"Siri is available in Beta only on iPhone 4S, iPhone 5, iPad (3rd generation), and iPod touch (5th generation) "
