iced tea

[Barnhart]

My curiosity has been stirred up.  In one of Popik's recent quotations
there is a reference to ice tea being more common in Texas.

>     "So much tea is consumed here year-round that you might even call
iced
>tea 'the national beverage of Texas.'  Historically, it is called
'ice' tea
>in Texas.  Iced tea was created by an Indian tea merchant who couldn't
sell
>his hot tea at the St. Louis World's Fair in 1904."
>--"Tea Pleasures," HOUSTON CHRONICLE, 26 July 1995.

I have not found any reference yet in dialect dictionaries as to the
dialect variation of ice vs. iced tea.

DAE has only iced tea.
DA has only iced tea.
WU3 has iced tea as the main entry and ice tea with a cross reference.
OED has no reference to either.
OEDs has no reference to either.
Cent. Dict. has only iced tea.
DARE has no reference to either.
AmDiDic has no reference to either.

Nexis shows 24,500 articles for iced tea
Nexis shows   4,200 articles for ice tea.

Has anyone a feeling for possible geographical or social distribution
for these two terms?
