Two different iPhone accessory makers have already announced cases compatible with the slightly-different design of the Verizon iPhone 4. As reported earlier, the Verizon iPhone has small modifications to the antenna and in particular the placement of the buttons that renders most iPhone 4 cases unsuitable. Case-Mate plans to have an entire new lineup available for purchase later this month, while audio accessory designer Scosche is promising to be ready with their case on or before the February 10th launch date with Verizon.
