White iPhone 4 appears in Vodafone inventory system (Updated)

Listings for the white iPhone 4 have appeared in Vodafone Germany’s inventory system, according to a new report. Citing an anonymous source who provided screenshots of the listings, Engadget reports that listings for both the 16GB and 32GB white models were found; the source said to expect a launch “soon.” Apple has repeatedly delayed the white iPhone 4 since its unveiling last year, first from June 2010 until July, then from July until late 2010, before being slated for a Spring 2011 rollout last October.

Update: Mac Rumors reports that similar listings have now been found in Best Buy’s inventory system, with a listed release date of February 27.
