We’d already heard mumblings that the white iPhone 4 would launch on the 27th, and now leaked photos of Best Buy’s internal stocking systems are solidifying those rumors. While the above screenshot only says “AT&T hardware,” 9to5 Mac suggests that Verizon Wireless’ CDMA version of the phone will also be available on the same day. Store are already stocking the devices for Wednesday’s launch, but there could be as few as ten 16GB and 32GB models per Best Buy location. Additionally, it’s being reported elsewhere that Apple stores have received promotional materials featuring the white iPhone 4, and should be receiving stock starting tomorrow. Hit the jump for another inventory shot.
