We’ve managed to get hold of a couple of very hot iPhone concept designs, that are part of the so-called “iPhone 4G” series. First, there’s the iPhone 4G Ultra, pictured below and packing a Titanium and glass case, an OLED display and 64 GB storage space.

iPhone Ultra comes with a 1.2 GHz CPU, a 5.2 megapixel camera, 4G support, WiFi, Bluetooth 10x and iPhone OS 2.7. The handset’s battery will last 18 hours in video playback mode and 48 hours if you play audio files. Another beautiful concept is the iPhone Deluxe (Luxe), with its huge internal memory of 128 GB and black, elegant case.

Luxe becomes the iGame if you attach gaming controls to it, turning the device into some sort of PSP console. The last of the new iPhone 4G concepts is the iPhone Long, a name that pretty much describes the idea behind phone. All of these designs were created by hdi, who did a terrific job.
