Case Manufacturer Mails 4G iPhone Cases to Wired.com

Apple’s iPhone-centric developer event is still days away, but a case manufacturer sent Wired.com two protective rubber cases designed for the next-generation iPhone.

The company, Gumdrop Cases, said it based the case design on a combination of specifications provided by inside sources in the plastics industry, as well as features seen in the prototypes leaked to Gizmodo and a Vietnamese blog. The company, which has offices in California, the U.K. and Hong Kong, said it did not receive the specifications from Apple.

“It’s supposed to be announced on Monday is what we’re being told, so we wanted to make sure we had cases available,” a Gumdrop spokeswoman told Wired.com.

The third-party accessories industry has historically been a leaky boat for Apple, according to Leander Kahney, Cult of Mac writer and former news editor of Wired.com. In the past, we’ve seen a number of case manufacturers begin selling protective cases for Apple products ahead of release. However, those leaks usually occur in China, and this is the first time Wired.com has actually received a case for a next-gen Apple product before it was released.

The characteristics of the two cases line up with the prototypes of the next-gen iPhone revealed in video and photos. Its overall form factor is slightly more square than the current iPhone. The case also fits awkwardly around the current iPhone: The holes for the audio/silent switch, volume button, power button and microphone jack don’t line up. The camera hole is slightly too large, giving enough room for a camera flash — a feature that Gizmodo and the Vietnamese blog saw on their prototypes of the next-gen iPhone.

A Gumdrop representative admitted the company deliberately mailed the cases, labeled “iPhone 4G Case” on a press flier, in order to gain attention prior to Apple’s official announcement of the product — you could call it a publicity stunt.

We have to get a next-gen iPhone to see if these will really fit, but the story about overseas insiders in the plastics industry is intriguing.

Apple’s Worldwide Developers Conference kicks off Monday, where Steve Jobs is expected to announce Apple’s fourth-generation iPhone during a keynote speech.
