Macerkopf.de reports that they have received confirmation from Germany's 3 carriers that the white iPhone will launch there on April 28th, just like Japan. That leaves us wondering if the rest of the world will also need to wait until Thursday. Signs had pointed to today (April 27th) as the launch date for the white iPhone.
It's still a bit early in the day, but there's been no peep from Apple or its U.S. carrier partners about the launch. Typically, Apple's store will go down in order to update. At this point, it seems likely the worldwide launch is indeed April 28th, so one more day of White iPhone 4 anticipation.
