Open iTerm here

Modified from Deep-blue's version. I don't use tabs in shells, so this version always opens a new iTerm window.

Open ScriptEditor from Launchpad and paste this in:

(*
    Open Terminal Here
    A toolbar script for Mac OS X 10.3/10.4

property debug : false

-- when the toolbar script icon is clicked
--
on run
    tell application "Finder"
        try
            set this_folder to (the target of the front window) as alias
        on error
            set this_folder to startup disk
        end try
        my process_item(this_folder)
    end tell
end run

-- This handler processes folders dropped onto the toolbar script icon
--
on open these_items
    repeat with i from 1 to the count of these_items
        set this_item to item i of these_items
        my process_item(this_item)
    end repeat
end open

-- this subroutine processes does the actual work
-- this version can handle this weirdo case: a folder named "te'st"ö te%s`t"

on process_item(this_item)
    set thePath to quoted form of POSIX path of this_item
    set theCmd to "cd " & thePath & ";clear;"
    if application "iTerm" is running then
        tell application "iTerm"
            activate
            set aWindow to (create window with default profile)
            tell current session of aWindow
                write text "cd " & thePath & ";clear;"
            end tell
        end tell
    else
        tell application "iTerm"
            activate
            set aWindow to current window
            tell current session of aWindow
                write text "cd " & thePath & ";clear;"
            end tell
        end tell
    end if
end process_item

Export it as an Application, then drag the application icon up to the Finder toolbar while holding down option and command.

Then you can click the icon in the Finder toolbar and iTerm will open at that folder.
