The folks at NaviGadget got a couple reader-submitted shots of a white Nuvifone, but there's no telling just now how legit they are. Garmin just shows a black version of its phone -- which is still slated for Q3 at a purported $500 pricepoint -- on its own site, but perhaps this teensy supposed leak means there's more news in store for the Nuvifone camp in the near future.
