The ever elusive White iPhone is trying to get attention once again with another teaser. According to Engadget, this Best Buy shelf tag was spotted this weekend at a Best Buy in Houston. Nothing surprising with the details: White iPhone 4 from AT&T at $599.99 without a contract, which is the same price as the black. With all the cliff hanging evidence of this seemingly mythical phone, we won’t be surprised if the white iPhone finally sees daylight within the next few weeks.
