Looking forward to picking up a Galaxy S III from Verizon this Tuesday? You'd better reschedule. According to the carrier's website, Samsung's latest Galaxy smartphone won't be available until July 12th, contradicting the previously stated July 10th shelf date. Don't get frustrated just yet though, we're hearing reports from readers that their phone has already shipped, or in some cases already arrived, suggesting that pre-orders are sticking to Verizon's original schedule.
