Following our post about an internal memo dictating a April 27th launch for the white iPhone 4, Engadget has nabbed three pictures of the device at Vodafone UK. Supposedly a customer was able to purchase the device with model number MC604B/A. The biggest thing we take from these pictures is the white iPhone 4′s new proximity sensor. Notice the new sensor is just a black cut in the white front plate versus the old sensor with dotted cuts. Perhaps the proximity sensor was the main reason for delay? Anyways, count us thrilled.
