Interview with Draco Design.... Q: Considering other aluminum cases cost in the $70-$150 range, what will be the retail price of the Draco IV aluminum bumper for iPhone 4? A: The DRAVCO IV comes with 6 different colors: blue, black, red, gray, silver and gold. Blue, black, red and gray colors are retail for $99. Silver and gold colors are limited edition with retail price at $119. Q: So many aluminum cases found on the market today suffer from signal loss (with the exception of a few), what's the mechanism you have used for minimizing or terminating signal loss in the Draco IV? A: We considered and studied how to reduce signal loss issue when developing and designing the DRACO IV case. So, when the DRACO IV is installed on the phone, the case frame is designed to mount (hold) to the glass surfaces of the phone both front and back, without physically touching the metal band on the side of the phone. And thats the key to minimize signal loss issue. Q: Does the Draco IV have support for other third party accessories, such as headphones, third party cables, etc? A: Yes, the DRACO IV is designed with compatibility and flexibility, so the case supports for 3rd party iphone4 accessories. Q: Will you be able to dock the Draco IV in third party docks? Yes, the DRACO IV can be docked in 3rd party docks. Q: How much lip does the case provide (lay on the table design, screen not touching the phone, only the case) on both the front and the back of the phone? A: About 1mm on both front and back.
