While all the banners still say Wirefly X Prize Cup ‘07, word is that the Internet seller of cell phones and wireless plans is decreasing its financial support for the upcoming X Prize Cup festivities at Holloman Air Force Base in New Mexico.

According to X Prize Foundation spokeswoman, Sarah Evans, Wirefly is reducing the cash — an unspecified amount — it will make available as lead sponsor of the October 26-28 rocket festival.

“Wirefly has been a tremendous partner for the X Prize Cup,” Evans told me. “With their assistance they have allowed us to achieve our goal of bringing live launches and education outreach to tens of thousands.”

Wirefly supported the X Prize Cup last year. But this year, things have turned sour.

“Wirefly and the X Prize Cup have agreed to reduce the financial commitment to this year’s show,” Evans said. “The X Prize Cup can assure our fans and participants that this will not affect the event in a significant manner. Our partnership with the Air Force has allowed us to expand our entertainment and education options at this year’s event,” she added.

All of the X Prize Cup partners are responsible for making the event a success, Evans said.

There’s likely more to come on this…so stay tuned.
