This tournament seems to have been incorrectly named in these forums.
For 2006 the title sponsors are Red Letter Days and the correct title is
"The Red Letter Days Open"
The tournament title change is part of an existing sponsorship deal which was agreed in 2005 between the Lawn Tennis Association and Phones International Group, who’s Chairman and CEO Peter Jones, jointly owns Red Letter Days following its acquisition last summer.
